VPN’s English name is “Virtual Private Network”. As the name implies, virtual private network we can understand it as a virtual enterprise out of line. It can be encrypted by a special protocol on the connection in the Internet two or more different places within the enterprise to build a proprietary network of communication between the lines, is like a special line set up the same, but it does not the laying of cables needed to really like the physical line. This is like the bureau to apply for green, but do not give the cost of laying lines, do not buy a router and other hardware devices. VPN technology has an important technology was originally one of the router, the current switch, firewall software such as equipment or WINDOWS2000 also supports VPN functionality in a word, VPN’s core is in the use of public networks to create a virtual private network.
Requirements for different users, VPN, there are three solutions: remote access Virtual Private Network (Access VPN), the internal virtual network (Intranet VPN) and enterprise expansion virtual network (Extranet VPN), these three types of VPN remote separately with the traditional access to the network, Intranet and enterprise internal networks and relevant partners in the enterprise network posed by the Extranet (external expansion) corresponds to.
VPN gateway is to achieve local area network (LAN) to LAN connected devices. Literally we can know that it can achieve two major features: VPN, and gateway. Broadly speaking, support for VPN (virtual private network) devices such as routers and firewalls can be counted as VPN gateways. Current common VPN gateways VPN gateway can include a simple, VPN routers, VPN Firewall, VPN servers and other products.
VLAN (Virtual Local Area Network), also known as virtual local area network, local area network is based on the exchange, the use of network management software can be built across different network segments, the logic of different networks end to end network. A VLAN form a logical subnet, that is a logical broadcast domain, it can cover a number of network devices, allowing users at different geographical locations to a logical network subnet.
The conditions set VLAN
VLAN is based on the physical network based on a logical subnet, it needs to establish appropriate support VLAN VLAN technology network equipment.battery Toshiba PA3480U-1BRS
When the network communicate with each other between different VLAN, you need the support of route, then you need to increase routing equipment – to achieve the routing function, either using a router, it can be used to complete the three switches.
The basic strategy by VLAN
From a technical point of view, VLAN classification can be based on different principles, are generally divided into the following three methods:
1, port-based VLAN classification
This division is to one or more of several ports on the switch by a logical group, which is the simplest and most effective division method. The method only network administrators of network devices to re-assign switch ports can be, do not consider the port of the connected device.
2, based on the MAC address of the VLAN classification
In fact, refers to the network card MAC address identifier, the MAC address of each piece of card and the only cure is on the card. MAC address of 16 hexadecimal numbers by 12, said companies identifies the first 8 bits, then 4 for the network card ID. MAC address of the network administrator may be some sites into one logical subnet.
3, VLAN-based routing by
Work in the network layer routing protocol, the corresponding work equipment routers and routing switches (or three switches). This approach allows a VLAN span multiple switches, or a port in multiple VLAN.
For now, the division of the VLAN major ways to take the first 1,3, 2 ways for the auxiliary program
Advantages of using VLAN
Use VLAN has the following advantages:
1, Broadcast Storm Control
A VLAN is a logical broadcast domain, through the creation of the VLAN, isolating the broadcast, reduce the broadcast range, you can control the production of broadcast storms.
2 and improve the overall security of the network
Through the routing and MAC address access list by VLAN allocation principles, can control user access and logical segment size, the different user groups in a different VLAN, thereby improving the overall performance of switched networks and security.
3,HP Pavilion DV6500 battery network management simple and intuitive
For the switched Ethernet, if the segment re-allocation of some users, network administrators need the physical structure of the network re-adjustment, or even need for additional network devices, increased network management workload. As for the use of VLAN technology, networks, a VLAN according to their functions in a target group or the application of Internet users of different geographical locations into a single logical network segment. Without changes to the network physical connection to the case of the workstation can be any working group or move between subnets. Virtual network technology, greatly reducing network management and maintenance burden, reduce network maintenance costs. In a switched network, VLAN provides a flexible combination of segments and institutional mechanisms.
Three switching
Traditional routers are routed in the network, firewall, isolating the role of broadcasting, and in a subsequent division of the VLAN network, the logical division of communication between the different segments will still be forwarded through the router. Since the LAN, the communication between different VLAN is a great amount of data, so that if the router to each packet on a route, with the network increasing the amount of data, the router will be overwhelmed, the router will the bottleneck of the entire network operation.
this case, the emergence of the third layer switching technology, it is the routing and switching technology combined technology. In the first three switches for routing the data stream, it will generate a MAC address and IP address mapping table, when the same data flow once again through, according to this table and not directly from the floor once again through the route, thus eliminating the router routing delays caused by network and improve the efficiency of data packet forwarding, the router may have to eliminate network bottlenecks. Shows three switches in one set of routing and switching, routing the internal implementation of the switch to improve overall network performance.
In a three-layer Gigabit Ethernet switches at the core, the management of different functions in order to ensure the convenience and security, and stability of the entire network operation, can be used by the virtual network VLAN technology. Isolated subnet VLAN broadcast storm, the implementation of some important sectors of security protection; and when the physical location of a sector changes, simply set the switch to the reorganization of the network can be achieved, very convenient, fast, while saving costs.

As early as before the birth of photography, body art had undergone two or three years old. Venus from the Stone Age to the ancient Greek sculpture to Renaissance, has handed down the fine body art. With the invention of photography 150 years, photography has also developed the human body, the formation of a different genre. In China, for various reasons, the body still in the initial stage of photography. Has been involved in or are preparing to try to impact the human body photography friends, increasing the understanding of these ideas is essential. To this end, the author interviewed photography theorist, Professor Han Zishan Central Academy of Fine Arts.
Q: The human body photography and portrait photography, performance targets are all human, what is the relationship between the two it?
A: From a large portrait photography broad concept, the human body photography belongs to a class of portrait photography, because it is people’s performance. But the narrow sense, portrait photography and the human body is different photography, portrait photography show is the human personality and inner spirit of the performance of the human body photography is the human form and structure.
Q: But the performance of some masterpiece portrait photography is the beauty of form and structure, but not the human body photography.
South Korea: photography portrait photography and the human body without strict limits, but different emphasis. Portrait or in the face, body, emotional attitude, such as performance, including more knowledge. Photography is the human body through the original structure of the human body to express different body language, contains a more emotional, such as life, beauty, charm the United States, the U.S. forces.
Q: Do you think that photographs of human aesthetic criteria?
A: The first is the beauty of light and shadow shapes. The shape of the human body photography, light to be beautiful, or creative. The kind of reproduction, Record of the method, not suitable for human photography. In addition, should have the social consciousness, to sublimation of human emotions, to arouse people’s self-esteem.
Q: Can you talk about the development of domestic human photography what kind of situation?
A: In China, human photography was a dangerous area, a few years ago is still a restricted area, after the reform and opening up a new change. I think that is still a hard nut to crack in the gray area, because the human body healthy and unhealthy vague demarcation of the photo.battery Toshiba PA3534U-1BAS

Q: From an artistic standards, you believe that the best photographs of body which should have the necessary factors?
A: Generally speaking there are three points: First, have aesthetic ideal, aesthetic, the artist’s personality and ideals must be lofty; Second, the United States have created the material means, can feel the beauty manifested; third is to have creative not allowed to repeat.
Q: From the creative side, the distinction between healthy and unhealthy boundaries of the human body what is it photography?
A: I think there are four lines:
The first is the creation of different motives. Artists making body, the shape of the performance of the United States, strength and life, such as the strength of the U.S. male body, female body’s tender, and curves. Artists face of the most outstanding natural creation – the human body, should have a noble pursuit. Those sex, unhealthy picture is of the pursuit of, sensory stimulation, primitive instincts, are more mediocre, and it is ugly.
The second is the creation methods are different. In principle, the human body photography should be placed shot is to get permission from the subject of a future cooperation between the parties and should not be taken in those who do not know the circumstances capture, photographed. Many pornographic photos are candid.
The third is the shape different. Photography should focus on the human body to light, the beauty of modeling the performance of the human body, the image of a sense of feeling so shy. I appreciate that cover half of the more subtle Banlu body works, not like some pictures of Japan according to the human body. And those who do not speak light, only the pursuit of exposure photographs, not to mention human body.
The fourth is the photography is completed, the human body as a work of art photography, the photographer is willing to be made public, social recognition and communication. Without health pornographic photographs can not see anyone.
Q: photographic images from the specific terms of the human body, health and unhealthy photos most obvious difference is what?
A: The health of light and shape by means of work, the performance of the beauty of life is the life of the hymn. The sex photos are directly exposed to the genitals, causing one of the sexy.
Q: The Development of foreign body photography how what?
A: Foreign body photography over 100 years of history, along with the birth of photography began. At first take the human body, people feel offensive. Because photography is different from the painting, after all, it is realistic, so the first story of the human body photography of Painting from the results. The real photo of the human body is from Edward. Weston started. He found the body, movement, gesture own rhythm, with light, lines show the structure of the United States, life beautiful.HP ProBook 4515s battery
This true work of art body photography is in no way pornographic factors. Foreign body photography has been developed to form a lot of genre, can be said to be flourishing.
Q: Foreign body photography school, what does?
A: The school has realism, creative camp, camp structure, imagery, etc., there are a number of different aesthetic pursuit, such as: Heaven and Man United, structural beauty, melodic beauty, philosophy beauty and so on.
Q: China does not develop the human body photography, which is the difference between Western concepts is not a great relationship?
A: Yes! Different foreign concept, sex also allows artistic expression. In China, several thousand years of cultural deformity, one is imprisoned, the other is resistance, and caused this difficult to judge. Overall, the domestic human body photography is the initial stage, model selection, economic conditions, development has limitations. Technically, the filming technique is poor, poor light, no major environmental.
Q: From the sessions of the National Photographic Competition Works, the human body works have appeared.
A: The restricted area has been broken, the door still not open. I think the country is not suitable for strongly advocated the development of the human body photography, there should be a process. Can start with a theme of the human body photography began, as the sessions of the National Photography Contest in the “Sky Goddess”, “Sun and others,” and so, implicitly performed some of the human body, so that the viewer, society can accept. In addition, the swimsuit is a human body photography, and now more of this photo, we can see traces of people to explore.
Q: In the human body photography, human body must be taken beautiful?
A: Not necessarily. U.S. does not mean beautiful, but beautiful in a beautiful, but there are different types of beauty, not to mention there are “ugly,” said. Rodin said: “In nature, most people called ugly, in the arts can become extraordinary beauty.”
Q: If the screen is only the local body, such as a leg or an arm, having a human body photography it?
A: There is a structuralist, that is, the performance of the waist, chest, buttocks, legs and other parts. Category definition is relative, there is no need unity. In my opinion, that the whole human body or structure or even with nature and the local performance of all if this is the human body. In addition, like those deformed human body, abstract human body, multiple exposure of human, etc., are emotional symbols are an expression of the beauty of life.
Q: Photography in the human body what a photographer should have the personal qualities?
A: The photographer should be more mature, understanding of the structure of the human body, the shape of the grasp should be skilled and have their own unique feelings and pursuit. Because photography is a serious human subject, again making sure to mature. The body is not in tune for beginners.

Photographic composition to highlight the subject in the simplest way is to subject living in the center of the screen. Because the characters and objects in the center of a rectangular screen, the photo has a special stability.
A · Deco Soviet photographer pointed out that this subject is located in the center of the screen composition method of dealing with the theme of one of the most effective art. However, in using this method, the composition should be very carefully arranged figures and objects, because the subject in the geometric center of the screen, often cause the picture seems to be rather dull. For example, some novice photographers who often were taken to the scope of characters placed in the center of the viewfinder, and let is facing the camera, his eyes watching the camera. Results photos appear dull, but have left around the same size as the screen blank. This mapping method, more suitable for shooting on sports subjects. Deco will be the general practice, photographic highlights of the main methods used,HP ProBook 5220m battery grouped into the following categories:
1. Made into a feature mainly object to or near the close of the middle ground, which requires shooting from close range, the range is only a small screen space.
2. The main configuration in the foreground, so the screen can contain a large enough space, become a panoramic photo.
3. The subject and background in the tone or color difference on the right, or contrast.
4. With a light emphasis on the main part of the composition, so that appears to maximize the brightness.
5. The main focus on accurate, so that some minor loss of sharpness or background.
6. So that the meaning of the screen to the center of the main assembly, and emphasized by spot, this method used for the performance of interior.
7. The main set in the center of the screen or near the center of the site.Thinkpad R31 Battery
If there is no particularly striking near the things, the audience will notice the first subject.
8. Shooting angle with the main emphasis. It should be noted, does not apply extreme angle of depression or elevation.
Deco believes that light is the most effective means of modeling can be fully used to emphasize your subject. Lighting conditions to highlight some of the following three-dimensional body shape and surface structure of the sense of space.
For example, the dark background and bright prospects and more. To emphasize the subject of space feeling of depth; dark about body shape outline of the background color can be portrayed well; Similarly, the light of the body in the dark background would make it very clear; expressive light and shade , on the surface level of a harmonious alternation of tone changes, so that similar objects appear with the original, Toshiba PABAS078 battery replacement
therefore, photos will show the actual living in your subject.
American photographer Catherine Carl Hoath that audiences are often the first note photos on the bright part of the picture, and will think that this is the center of interest. Therefore, when caught in the shadow of your subject, he suggested two alternative methods highlight the subject, “the most feasible method is to be close to the subject and try to avoid the area around the brighter. If it is not, then auxiliary flash can illuminate your subject slightly, or not too large in contrast to the case of light, using a white reflector or mirror, extra light reflection to the main body. This will also help. or even to photograph exposure over, that is, the shadow area in accordance with the exposure to make the picture brighter in the partial loss of level. Although the latter technique is more difficult to use, but in some cases may be inadequate to deal with the main lighting, better way, because it also can weaken the background color. “

Fireworks can be described as more difficult to shoot subjects in a class, first it is dynamic, which requires us to take into account the exposure time and the second will affect the surrounding environment, the observability of the photo, there are also such factors as weather the effect of the shooting.
With the general night shooting of fireworks is very difficult to photograph satisfactorily, and needs to take into account the height, size, speed settings, aperture, shutter speed and so on, if the lack of experience, all good grasp. Comprehensive test of the photographer’s technology, opportunities to see nature and composition. Because fireworks are dynamic and irregular, and give a simple example: a site launched with two of the same species of fireworks will not bloom at the same height and position, even not the same size, there is randomness. Beautiful fireworks fleeting, when you rush, when the fireworks have disappeared in the night sky brightness under a different shape and duration of the fireworks turn to the. You never know how the next kind of fireworks.
If you have some skills in making fireworks, it touches help to reduce the waste film shooting rate.
First, we must clearly understand that the shutter the camera will record the time at the track all the lighting, and set in a photograph, while the shooting range in the strength of the various positions of different intensity of light throughout the contrast for photo appear bright or dim, and our eyes see is not the same. The principle of photographic experience in general people will know. Then we can learn the skills of shooting fireworks.
First, the preparatory work: tripod, cable release, black cardboard, location, wind direction and wind.
Sufficient battery power,HP ProBook 4425s battery tripod and remote shutter cable release or to bring the best, because it is low-light shooting, need a long shutter exposure time. If necessary and then put on a black cardboard, its role in the following description of the fourth point again.
Then, shoot fireworks site is selected, if the big scene to shoot the fireworks, the best height, while nearby buildings had to play the role of the fireworks set off even more interesting, because from the simple principle of composition, there are reference more vivid contrast to the picture, if only shooting fireworks, you can not make the audience know how the fireworks, with the buildings contrast, it will become even more spectacular fireworks. When shooting landscapes to mean that we need to put some people sometimes shoot into the same. If the best qualified proposal to step on point during the day.
Also note that the weather that day, pay attention to wind direction and wind, windy weather is a good day for shooting fireworks. Air humidity and high visibility is also conducive to the shooting of fireworks. However,HP ProBook 4420s battery if the wind is not enough or no wind you will have trouble shooting it, because there will be fireworks and the release of smoke have finished, the smoke will be dispersed as soon as possible if you do not reduce or even cut off the next fireworks effect. I have encountered in Zhanjiang, a fireworks show, there was no wind, fireworks and put too close, the result can only see the foggy all the fireworks exploded the moment the bright spot, but do not see the fireworks and open process, do not that shot. So the weather event of such plans or cancel the shoot it, then it would have to shoot a few fireworks to seize the top.
Also try not to shoot at the upwind and downwind location of the fireworks, if wind-borne smoke will affect your line of sight to the wind, then the white smoke after the fireworks into the background, the bright light of fireworks.
Second, the shooting parameter settings: focus, white balance, sensitivity, shutter speed, aperture, metering techniques
Find a good location, good tripod stand, connected to the shutter release, the next parameter is the default shooting.
Let me talk about some of the more fixed parameters, the focal length manual focus mode is set to infinity; This is because you do not know the location at which the fireworks will be open, you can not know in advance the focus. White balance settings for machine-specific,Canon BG-E9 battery Grip because different brands and models of machines may have some differences. If a digital machine can wait for the fireworks show the process of trying to pre-model or warm fluorescent light shooting mode to try two, and then compare them more to behold your appetite Zhang is still not satisfied, then you can further fine-tuning, the general digital SLR will have white balance fine-tuning the machine functions.
Camera sensitivity (ISO) setting is not too high and too low, too high will generate noise and affect the photo quality, low shutter speed shooting the impact or lead to underexposure. In the author’s experience, sensitivity is set between ISO 200 to ISO 400 would be more appropriate.
Exposure of the remaining portfolio is most difficult to control: the aperture and shutter settings. We seize the most important point: that the planning of the fireworks display with a certain regularity, not all of a sudden blossom, while a rise to explosions of fireworks from time to disappear usually takes five to six seconds, and the most beautiful time should beHP ProBook 4325s battery 2,3 seconds before the time. Therefore, we control the shutter time like this time, of course, the fireworks have different different exceptions, short observation is important, if we want to take a full fireworks, but can not let the fireworks of the next screen, then To open the shutter when the fireworks up the next fireworks fireworks occurs even before it disappeared in the closed shutter.
So how to set the exposure combination of it? This describes a technique for the novice, before the fireworks display began on the surrounding environment with the camera metering, if there is a bright neon lights as a reference better, shooting mode, first hit the shutter priority mode “S”, the shutter transferred to 2 to 3 seconds, then you get the aperture value, such as F8, but this is not shooting fireworks aperture used, since the brightness of the fireworks when the outbreak of the environment you would surely be high, so good, we look for imaginary the brightness of the fireworks in the aperture on the further increase to transferred to F11. Well, experience tells us that if the smaller the aperture value, then the requirements of the shutter time will be smaller, meaning that the shutter with adjustable rate will be. But if you have neon lights from the buildings close to the location, then the fireworks will be relatively dark sky, then you need to adjust the aperture a little bit, there is no need o be too much, because then the performance might not be the object of fireworks.
Well, then we can hit the manual shooting mode “M”, set above the aperture F11, shutter doors open to the B (if B does not have the door to the longest exposure time used in that file) and wait fireworks appear. When taken to the first films, if not satisfied, you can immediately adjust the aperture value.

Many of my friends think computer is very mysterious, but in fact the computer is a “simple” complex machines. It is complex and profound because the computer works, many components. That it was “easy” because we use it in the process, no need to ignore those esoteric things, to use with TV sets, VCRs no difference. For example you use the TV remote control to select the channel, TV channel programs to appear on the TV screen. Similarly, some of you give the computer instructions, it will by instructions to give you a satisfactory result.
Therefore, the computer is not difficult to master. General two-step introduction to computers, first look at the basics of computer hardware, and then learn some commonly used software. If you think about to improve, depends on your interests Suozhi the.
Now, let us work together to visit a typical home computer. Take it easy, though the computer is a high-tech items can, but it is very approachable, understanding of the computer company, you no longer feel that computers are very mysterious. Family members often host computer, monitor, keyboard, mouse, speakers. There are printers, although not belonging to the family computer, but it is a close neighbor of the family computer. Host, is the computer all the family’s large mains, the equivalent of the human brain, almost all documents and information by its head, you want to work done by the computer is responsible for it, it will give other family members allocation, other family members so called peripherals. How host specific, we also detail later.
Display, its mission is to large mains and think they wanted to show everyone to see, so is the main output device, which consists of a video cable connected to the host graphics card. Previously,HP ProBook 6460b battery we multi-purpose 14-inch (diagonal screen length, 1 inch = 2.56cm) of the spherical display, but now has a 15 inch flat rectangular display is increasingly popular, and this monitor’s screen almost in a plane, no as the middle of the display as previously raised, the picture has been greatly improved results.
Keyboard, it functions like display contrast, is responsible for large mains in the “Enter” user requirements for the work of large mains. The user’s instructions must be told through its large Explorer. Through it, the Explorer, to know what to do.
Mouse, over the years with the popular Windows graphical interface, keyboard commands are basically no longer used, as long as the left mouse button or by operating the right to do what you can tell the large mains. Although it is small, gave computer users a great deal of added convenience.
Speakers, exclusive family of multimedia computers, and now, sound has drawn more and more growing family of multimedia computers,Del Inspiron 1440 AC Adapter attracted a lot of computer enthusiasts, the voice of large mains to tell by the sound card speakers, and then conveyed by it, and now a multimedia computer sound getting closer to the level of the home theater.
Printers, although the computer does not belong to the family, but very close relationship with them. As the monitor, printer is also a commonly used output device via a parallel cable connected to the host behind the parallel port. There are three types of printers: dot matrix printer, inkjet and laser printers, and its performance is progressively increasing.
To better understand how computers work, we’ll take the time to focus on the family of the host computer look great explorer. In order to explain the convenience, we split up the host, its main component is the motherboard, memory, hard drives, floppy drives, CD-ROM drive, sound card, video card and modem.
Motherboard is the backbone of the host large mains, most of the equipment had to through it together; this CPU,Canon MB D10 battery Grip English name Central Processing Unit, which means the central processor, which is the heart of large mains, unified command and dispatch computer all the work. We usually say 486,586,686, Pentium, Celeron, refers to a different CPU.
Memory, the English called Read Arandom Memory, referred to as RAM, a computer data information stored in the working process where the unit is called its “trillion” bytes, with “M” that (1M = 1024K, 1K = 1024 bytes, 1 characters two bytes, 1M approximately 50 million Chinese characters), we have omitted the normal “byte” word, only the “trillion.” Now the machines are generally installed 32M or 64M of memory. Hard drive, is usually stored files to install all the software and place, equivalent to host large mains in the stomach, the user’s WIN98, games and all correspondence on file here, before a smaller capacity hard disk, only a few megabytes, the current general has 6G, 8G or 10G more than the large-capacity (1G = 1024M).
Floppy drive, divided into 3-inch and 5 inch two,Toshiba PA3331U-1BRS battery
are now commonly used 3-inch floppy drive, can read and write 3-inch floppy disk can store 1.44M bytes of content, you can copy a file using a floppy disk to another computer, you can also the main copy of the file information on a floppy disk to prevent loss of data when the computers are down.

  
 
  
Find hidden in the QQ “ghost”
If you have friend somehow can send you some files such as “Video Girl” links to your conveyor virus, do not blame your friends to deliberately make trouble because he is also a victim, his QQ by the virus attacks, automatically radiated toxic. Vanguard of anti-crime issue from Suzhou, Wang Qiang is necessary to ferret out hidden in the QQ “ghost”, but also a clean and Netsky.
Anti-crime Vanguard: Wang Qiang City: Suzhou
Using the system: Windows XP SP2 descriptions of the symptoms
Shortly after the Internet today, received a number of QQ friends rave information, which makes me very puzzled. One asked to know, but they have received my QQ sent the information of all kinds of mess with the virus file, and also with the news. And the name of the virus file also varied, and made me very puzzled, do not QQ stolen? Then re-apply a QQ number, together with a friend, and within three minutes, it received the request to receive the file. And with virus files. Is my QQ virus attacks? Think of a few days to install a downloaded program, an error window pop up. Was not feel right, so an immediate anti-virus, but did not find any virus, it now appears certain is this program in “trouble”.
Find the clues to open the Task Manager to view, find a file called “the Rundll32.exe process. Common applications rarely call the Rundll32.exe, the most commonly used Rundll32.exe that some rogue software, or Trojan backdoor, It seems that the Rundll32.exe most suspicious.
Click the “Start” menu, search for files or folders “command,Toshiba PA3356U-1BRS replacement battery
and then find the Rundll32.exe” keyword. The results also found in the system directory of the SYSTEM and SYSTEM32 folder Rundll32.exe trace. By resolution of the file icon, I soon found a suspicious file, because fake Rundll32.exe actually to WINRAR icon (Figure 1).
Figure 1 find a suspicious file, I began to prepare to find the start of the virus. Run the Registry Editor, the same search for “the Rundll32.exe” keyword, the results did not find a suspicious startup items. Since there is no suspicious startup items, I decided to remove the virus, restart the system and then check the system processes, and did not find the Rundll32.exe this process, QQ is good news to friends, when I start the “hateful” the process of appeared. Rid of the virus
It seems that the QQ virus did not imagine so simple, it must be a file protection technology, so that when a file is deleted, other documents will soon generate a Rundll32.exe file a copy of. Just observation and the previous inspection, I think this QQ virus not start with the system to start, followed by the start of QQ. QQ installation directory then immediately came to check and then find a WINRAR files as icons name “TIMPlatform.exe”, in addition also found that a named “TIMP1atform.exe (Note 1 is not L) file (Figure 2).Dell SMARTSTEP 200N Replacement battery

Figure from 2 TIMPlatform.exe (note that not 1) use QQ and TM external application development interface management procedures, belonging to the QQ 2004 edition, to become an integral part of the underlying core modules. View of the file attributes, found “TIMP1atform.exe” This document is developed by Tencent. It seems this QQ viruses changed its name to be formal TIMPlatform.exe the “TIMP1atform.exe, the virus itself instead of QQ in the program. Order to completely remove the virus, the system by the time properties of the system search function “TIMPlatform.exe search results also found that the two documents. The first end the Rundll32.exe this process, and then just found out that the two documents and the Rundll32.exe, TIMPlatform.exe removed. Then modified virus TIMP1atform.exe “restore” TIMPlatform.exe.
Detection, the system again and found the association of the registry Chinese and executable files to be changed immediately to repair it through the Super Rabbit, the ultimate success of the virus is completely cleared from the system. With the gradual increase of QQ users,pavilion hdx16t battery QQ has also become more and more breeding grounds for viruses. In fact, a little some programming capabilities of the user will be able to write a similar virus, even if it can not write can transform someone else to write the virus to spread. It also makes this type of virus size is getting smaller and smaller, more efficient, endless variety of new viruses or variants, it makes a lot of anti-virus software now struggling to cope with, it is difficult for killing the first time.
Wang Qiang in checking suspicious files, first of all proceed from the system directory, did not completely remove the virus, check the other directory, and ultimately successfully cleared the virus itself. We face the hazards of this virus can also use anti-virus software manufacturers to develop Zhuanshagongju for killing. QQ Thief killing tools QQKAV, QQ tail Zhuanshagongju (Figure 3), can easily deal with these common QQ virus.

intel SNB platform Jingxian chip gate
1 May, the United States on Monday, Intel Corporation officially announced in early January this year, just with Sandy Bridge Series “second-generation Core architecture processors’ launch of the 6 series chipset (codenamed Cougar Point) found a design problem. Although Intel has designed the chip level that has been amended, but the revised version of the chipset in the new pre-market, Intel has decided to suspend all around the world 6 series chipset shipments.
SNB latest intel chipset platform
The chipset in question covers all Couger Point products, including P67, H67, and other sections of the mobile, commercial model. Intel’s official description of the problem exists in the SATA controller modules, “In some cases, SATA interface degradation may occur over time status, affect the hard disk, DVD drive SATA devices such as the performance.”
In the ensuing conference call on a special, Intel further explained that this problem exists in the circuit design 6 series chipset provides four SATA 3Gbps interface, specifically the interface circuit in a PLL clock tree transistors. The very low voltage transistor can only switch, but for its Intel imposed in the design of high voltage, resulting in high leakage current. Over time, increasing the leakage current may eventually lead to complete failure interfaces.dell laptop battery inspiron 1545

From the user perspective, the problem is with the use of performance time, the board four SATA 3Gbps interface bit error probability may appear higher and higher, until the device is completely unable to connect.
It is noteworthy that the first 6 series chipset SATA 6Gbps interface, adding the two do not have this problem. Therefore, if the notebook design, using only two SATA 6Gbps interface (SATA 0 / 1), then the problem will not be affected. DIY user in order to avoid problems, you can also try to SATA devices connected to the two SATA 6Gbps interface, or a third party to provide the SATA interface on the chip.
Intel said in a shipment of more than 100,000 6-series chipsets, the company began to receive a chip set SATA interface for fault reporting. Until early last week,Toshiba PA2487UR battery
Intel has finally succeeded in the laboratory to reproduce the problem, and then after several days of research has identified the problem, come up with a solution. In the final on Sunday evening, Intel decided to suspend all 6 series chipset shipments, and publicly announce this event.
Since the problem is the chip circuit design level, can not drive, the software correction, Intel chips will be manufactured in the photomask stage, replacing the metal mask layer to be addressed.Inspiron 1545 dell battery In fact, due to problems inherited the old transistor design are non-essential circuits, Intel needs to do is to completely disable it in the circuit in a transistor only. And the problem is the circuit design in the latter part of the updated Intel in step B was introduced last year to provide testing of the product but there is no problem.
Updated design and re-create the new 6 series chipset will begin shipping the end of February, April, returned to normal production output. Future new products such as Z68 chipset release schedule will not be affected by this incident, is still expected to release in the second quarter of this year.
6 series have been sold for the chipset, Intel and OEM partners that will receive the returned product, and plans to pay all the affected chipsets, amendment or replacement costs. The user does not need too much tension, their hands of the 6 series chipset can be assured that the system is still normal, patiently waiting for manufacturers of replacement and maintenance program came out. Because although the problem has been confirmed,but in fact the user under normal use conditions, three years, there SATA interface failure rate of only about 5%.
As the machine, replace the motherboard product to be recalled, is expected to Sandy Bridge platform, PC, laptop or 6 series chipset will be out of stock at least until the end of March, the company originally expected to launch in February, a large number of Sandy Bridge platform for new products almost certainly will delay publication.
Reason: The chip giant indeed affect the whole body, and good public relations are handled properly the Intel crisis, swift and strong response to this tragedy as comedy becomes the ability to hope that everyone can learn.HP N193 Charger

Thin, high capacity, long life, these are the outstanding characteristics of lithium batteries. For this reason, lithium-ion battery, it has rapidly replaced the nickel-metal hydride, nickel cadmium batteries role as notebook computers and other portable devices for optimal battery life. Recent times, continuously exposed laptop battery explosion, the laptop battery time and time again into the cusp, the user can do this lingering fear, the source of lithium Aspire 5315 Battery in the end is the driving force or a time bomb?

Study to find the mystery of the battery fire

In general, the current notebook lithium batteries themselves have a more comprehensive protection. It not only from the series / parallel composition of multiple batteries, the circuit board itself also contains two modules: the protection circuit board (Protection PCB) module and Smart Battery Gauge Board module, its design includes a set of battery protection first-level protection IC (to prevent battery over charge, over discharge, short circuit), the second-level protection IC (to prevent a second over-voltage), fuses, LED indication, temperature control and other components.

In the multi-level protection mechanism, even in the power charger, laptop unusual circumstances, the VGP-BPS9 battery can only be converted to automatic protection status, if the situation is not serious, often still work after re-plug, not explode. Laptop battery explosion face serious facts, the reporter sought the advice of professionals and power of a well-known manufacturers of design engineers.

According to analysis, nothing less than the lithium VGP-BPS13A/B battery explosion caused by a short circuit or overcharge, most likely when one is in the manufacture of lithium batteries, because the manufacturing process itself is flawed, leaving the existence of product safety problems that may occur at any time, such as should be insulation between the two poles of metal dust or copper foil and aluminum foil membrane perforation burr, resulting in micro short circuit. The former situation is most serious, it will directly cause a short circuit, and a lot of heat, resulting in vaporization of some of the electrolyte, the battery cover stretch.

In addition, there is a special case, the power charger or laptop due to special reasons, the lithium SONY np-fs12 battery to provide instant high voltage / high current caused by severe over-charge, such as the charging voltage by a sudden rise to 12.9V 12.6V or even higher, then there will be a high charging current generated within the circuit should move off the battery charge current, but because of some lithium battery charging over voltage, over current protection design is weak, which may cause damage to the battery protection IC, so that the laptop battery to protect the function of the damage, charging over the needle after the pole piece on the crystallization of lithium metal, piercing point resulted in a number of micro short-circuit, causing the PA3535U-1BAS battery temperature is gradually increased, until eventually the battery explosion, fire is occurring, This is a lot of laptop battery “hot” the main reason.

Add a layer of umbrella cover

At present, protection from the battery point of view, the battery pack before charging part of the traditional chip makers are played most of the programs provided precise control of charging voltage and charging current role in the over-voltage and over-current control does not provide the appropriate solution. Thus, the protection of the canon battery pack is completely dependent on the battery itself, such as over charge protection, over discharge protection, over-charging current protection, over discharge current protection, thermal protection and so on.

Protection in place need to prevent the first-level protection IC MOSFET failure or short circuit caused by over-voltage fault, so the second-level protection IC is generally considered to be the protection of the battery group last line of defense. In this regard, Bump E (O2 Micro) product manager for Hong Shizhen expressed different views, he believes that the protection for the VGP-BPS2 battery pack can move forward, additional control functions through the charger to achieve detection and control of battery charging action , which will undoubtedly further enhance the level of protection to the protection of lithium batteries with security.

To this end, the O2 Micro power management for portable devices developed by Cool Charge solution which combines the one called Cool Battery Technology battery protection technology, its greatest feature is a traditional chargers generally do not have the OVP (over Voltage Protection) and OCP (Over Current Protection) function of the two NIKON en-el9 battery protection, the technology has been embedded in them Cool Charge IC chip.

By Cool Charge IC chip, the power charger will largely assume responsibility to protect the battery. Under the control of the Cool Charge IC chargers, compared with the traditional design (see Figure 1), the need to significantly reduce external components, eliminating the need for Q3 and Q4 part of the design and reduce the failure rate. Q1 preserved and in Q2 (to improve the original design elements) between, Cool Charge IC set up a detection point, through the factory settings, the detection point of voltage and current settings are set slightly less than the Latitude D600 Battery manufacturers safety requirements. Thus, in charging voltage or current exceeds the Cool Charge IC to set the value of the security after the voltage or current, IC to control the Q2 off, first cut off before the battery charge protection; from detection frequencies, the detection time for battery protection ms interval level, and through the chip to detect, can be very easy to implement millionth of a second level, you can use a high frequency of continuous detection, the first step to achieve the purpose of protecting the battery pack.

How to Compare Compaq and Toshiba Notebook Computers
When comparing Compaq or Toshiba laptops, keep in mind the reason and purpose for the notebook computer. Different designs are geared towards specific markets, such as general use, business and gaming. Compaq was purchased by HP in 2002, so there are very few Compaq laptop models to choose from.
Size
Size, weight and durability will be key factors. Measurements to consider when comparing Compaq and Toshiba notebooks are the diagonal screen measurement, the depth and the weight.
Processors and Memory Dell Latitude D620 battery

AMD (Advanced Micro Devices) and Intel are the most common processor brands. The remaining Compaq models use AMD processors. Toshiba (and HP) laptops offer both Intel and AMD processors, depending on the model. As with any computer, a faster processor gives quicker load times, and more RAM (Random Access Memory) enables multiple applications to run simultaneously and more smoothly.
Graphics, Personalization and Display
A better graphics card will produce a better and faster image. Displays are either LED (Light Emitting Diode) or LCD (Liquid Crystal Display); both produce a sharp image. Personalization generally does not improve the actual notebook, but enhances aesthetics. Dell Latitude D630 battery

Drives
Hard disk drive capacity is often given in gigabytes (GB), with the access speed in RPM. Most notebook users require less storage than those working in graphics-based environments or with multimedia-heavy requirements. Both Toshiba and Compaq’s notebooks come with DVD writers and can be upgraded to a Blu-ray ROM.
Networking, Power and Bundled Software
An internal wireless network card allows you to connect Compaq and Toshiba laptops to the Internet through an Internet service provider (ISP). A wireless card with Bluetooth enables more than one application to use the device at the same time. Both Toshiba and the Compaq notebooks come with 6-cell lithium ion batteries. Compaq offers an optional "secondary battery", including a 9-cell extended-life battery.Dell Inspiron E1505 battery

Genuine Windows 7 Home Premium 64-bit is the standard Operating System (OS) for Compaq and Toshiba laptops.
Warranty and Protection Packages
Toshiba has a one-year standard limited warranty and can be upgraded to a two- or three-year package, with the option of extended service plans. Compaq offers seven different HP Total Care optional packages.
About Toshiba Notebooks
Japan-based consumer electronics manufacturer Toshiba Corp. entered the notebook (or laptop) personal computer market in 1985, soon establishing the brand name Dynabook, which it borrowed from a concept that computer scientist Alan Kay had developed in the late 1960s. By 2007, Toshiba had achieved worldwide cumulative sales of 60 million notebook PCs. This has contributed to Toshiba’s current standing as the world’s fifth-largest producer of PCs: behind only Hewlett-Packard, Dell, Acer and Lenovo.
Divisions dv6 hp battery

As of 2011, Toshiba Corp. has six families of notebook PCs. The company gears the Satellite Pro towards budget-oriented small-business or corporate users, while customers less bothered about the price of a business-oriented notebook usually go for the Tecra. Toshiba Satellite 1400 adapter The Qosmio laptop is the most expensive and powerful Toshiba notebook, ideal for those looking for a multimedia machine to handle more intense computing activities such as PC gaming. The Portege are the convertible-tablet entries, while the Portable comprises netbooks: smaller, stripped-down versions of notebooks. Toshiba Satellite 1405 adapter The Satellite functions as the company’s flagship line, combining the characteristics of the mentioned lineups.
Size And Display
As the smallest notebooks that Toshiba offers, the Portable computers, comprising the NB500 and NB300 series — labelled the Portable Value and Portable Style, respectively — have 10.1-inch screens. The Portege is second only to the Portable, with choices between a 12.1-inch and 13.3-inch.Toshiba Satellite 1410 adapter The Satellite lineup has the widest selection of sizes: 13.3-inch, 14-inch, 15.6-inch, 16-inch and 17.3-inch. The Satellite Pro leaves out the 16-inch, and the Tecra also omits the 13.3-inch, 16-inch and 17.3-inch. The lone Qosmio notebook, the X505, is the biggest Toshiba laptop PC with an 18.4-inch screen.
Main Features
Toshiba’s Portable notebooks omits an optical drive for accommodating disc storage formats such as CDs and DVDs, and it comes pre-loaded with the 32-bit Windows 7 Starter, which is the version of the Microsoft Windows 7 operating system with the least amount of features. Other notebooks receive the more generous Home Premium instead. The Satellite Pro, Tecra and Portege laptops in particular,Toshiba Satellite 1415 adapter though, get the Professional edition due to their corporate-use orientation. The non-Portable machines also get more powerful processors from Intel or Advanced Micro Devices, and more hard drive space. As the top-tier Toshiba notebook, the Qosmio usually gets a quad-core processor as opposed to the Portable’s single-core chip or dual-core chip of the other line-ups. It also has a dedicated graphics processor unit from Nvidia instead of a motherboard-integrated Intel controller.
Pricing
With a starting manufacturer’s suggested retail price of $1,299.99, the Qosmio is the most expensive Toshiba notebook. On the other side of the spectrum is the Portable, which has starting MSRP prices of $299.99 and $379.99. As for the Satellite, Satellite Pro, Tecra and Portege, they have starting MSRP price ranges of $349 to $699, $599 to $899, $899 to $999 and $899 to $1,299, respectively.

Many hardcore buyers know, ebay merchandise for sale on the market price is definitely lower than that! Because the choice of buyers on ebay very much, we found dozens of similar goods hundreds of sellers, so the seller to ensure the product quality, price advantage has become their competitive advantage, sellers set the sale price they can afford are basically the bottom line! So how do we minimize the seller under the conditions of the profit, spend less money to better baby do? How to bargain on ebay net too! Here is the seller’s point of view come from a small series of a few experiences, hopes buyers can get help here:

1.good attitude, courtesy of consulting the seller questions.
 This is very important! Many buyers come on is this: in?, How much of this stuff? , To a lowest price now! Yes, the buyer is God now, so some details to ignore. Just think, the seller would like to thank you for coming though, but if you let people feel uncomfortable, my heart will form the first resist emotions, again wanted a bit difficult for the seller discount.
Summary: bargain should be polite, talk with the seller as much as possible on the taste, even as a friend, so many feelings to help you win more concessions.

2.moderate praise, tell the seller of goods sold her like you
People like to praise their own people! Just understand this, in many places will have unexpected harvest Oh! And sellers in the exchange, the seller is to make modest concessions to popular recognition with a move, such as you fancy a ring, you can say you like this ring, hopes dispensers to oblige, for a discount or something !
Summary: the seller of goods sold recognized, psychological will to some extent, guard, buyers must be at the right time to seize the opportunity, take advantage!

3.to find low-priced goods like to compare, let the seller know the price of his sale price there is room for
Try to find a similar product to the sights of home sellers just do not see the price, in order to lower prices!
similar products on ebay very rich oh, so afraid of can not find the same product!
Summary: does the seller to see similar products price than they sold in the low post, under normal circumstances do certain price concessions

4.haggling with the seller, try to reveal themselves very familiar with the goods, such goods have to know how much profit marginsHaggling can be said that they are experts at knowing how many of these products can give concessions, requiring the same treatment! Then the seller will usually try to compress profit margins, give you a discount price!
Summary: If you really like an item, it must have some knowledge, know ourselves, know yourself.

5.diversion, the cover of darkness
To lock their favorite thing than a better quality, more expensive goods hard bargain. Cut into them later in fact, want to buy another, and this quality to be satisfactory, so you can just cut a good price and then cut.
Summary: This move must be skillfully applied, or to feel cheated by the seller, the effect will be
counterproductive!

6.buy more items, so that sellers discount
If more than one shop goods are like, can be bundled with purchase, and asked the seller discount. In this case, the seller is no reason to refuse!Such as buy a HP Probook 4535s battery and also buy a HP Probook 4535s charger related at the same time.
Summary: This is the purchase of goods law, but the issue of how much the seller will offer

7.Offer is not necessarily reflected in the price, buyers want to learn to pilfering
Landlord met a buyer, he bought a 89 yuan of earrings. We have developed the promotions are over a hundred gifts, but the buyer Ruanmoyingpao, we do literally sent him a gift worth $ 18. Doing basically no profit, but the whole atmosphere is very good talk on when it paid a friend
Summary: Sometimes deals do not necessarily have to be in cash, more useful if more fishing products also comes with quite a bargain.

8.Thirty-Six, go to the
This will be used for each seller a move, and final nirvana! “Dispensers, does this pendant can offer you?” “Hello pro, I’m sorry, we price a release, no bargain!” “So expensive ah, can play a 10% discount it?” “10% off? ! how that line, which are not defective … … Oh! “” pro, free shipping for you? … … Oh! “” up to avoid rush delivery and then guiding da … “” Oh, forget forget, even to make friends now! ”
Summary: On the wrong Batui left is haggling master the routine use of a common tactic on move on
