 Several new malware propagation mode Alerter l'administrateur Recommander à un ami Lien de l'article 

Even if you are a computer high hand, a very rich computer sony vaio vgn-nr11z/s laptop keyboard knowledge, you also can't guarantee you surf the Internet must be safe, because the new malicious software always appear, and new mode of transmission will arise in the network, if know to the form of credit card data input before find safety lock logo, or you never open from strange the sender email, also cannot prevent some new ways, network threat to still have the chance, the place from can't imagine to step in.
 
Below is the new malware propagation mode, Internet friends to pay more attention to:
 
1. Download pirated movies, software or music. College students' love these sites, because they can find they need but don't want to spend money to buy all the media. But in the file exchange website to find your music, as in dump to find a big meal: maybe can enjoy a toshiba satellite a505 laptop keyboard meal to eat to the full buffet, but is likely to be infected with what's wrong with it.
 
2. Micro bo is the abbreviation of the site (i.e. say usually short address) is a kind of new mode of transmission, abbreviation website let whole website easy to read, but you don't know where to go, there are many network on site for the service, as long as the input abbreviation network address, can let you can see complete URL, though not necessarily is safe web site, at least let you see the original source. The safest way, of course, is to use a malicious web site intercept tool network security software.
 
3. Search for hot topic. "Black_Hat SEO search engines poison" the toshiba satellite l500 series laptop keyboard hacker to let some packaged malicious link in the search engine's live on before the term structure websites or web pages a kind of technique. So the next time when you use the media attention big celebrity or well-known things a conducting a search, you click on any link before a Muse search results link. For the safety, the best is a click into the things you have heard the mainstream website.
 
4. Installation silly anti-virus software. If you're distracted, or if you just see the bomb window appear to you to take action automatically when click "OK", it is likely to accidentally installed the latest version of the Fake anti-virus soft a Fake AV. Fake anti-virus software is a warn you infected with malware warnings to spread. If you agree to download any kind of their promotion of anti-virus software, finally it was possible on the infection is that you try to avoid malicious toshiba satellite l555d s7930 laptop keyboard software.
 
5. Mobile phones use positioning web sites and services. Through such as Foursquare this kind of service will make your friends can always know where you are, just think a clever and intention irregular stranger can how to use this data, is still pretty let a person hair bone of SongRan.
 
New malicious software makers usually use a legitimate web site, such as daily millions people browse news website, can solve the problem before flow down a ticket victims. Good toshiba satellite p500 laptop keyboard behavior and caution is the premise of safety on the Internet. But this is not enough, this also is why use good anti-virus software, and time version update is still a very important thing.

 How to set up the computer motherboard jump line Alerter l'administrateur Recommander à un ami Lien de l'article 

Motherboard jumper hp g42-101xx laptop keyboard Settings is onboard maintenance must grasp foundation. A, knowing the jumper wire type so far, jump line has been the development of the three generations, respectively is key cap type jumper, DIp type jumper, soft jumper. 1. Key cap type jumper key cap type jump line is composed of two parts: the base part and key cap part. The former is upright two root or three root disconnected needle, the adjacent two needle decided to a switch function.
 
To jump line operation only sub and off two. When using a jumper, namely sub a jump line, it will be a can make two needle connected key cap to it, so that both take two needle is connected to the function of the jump line should have. Otherwise, can will key cap only with a needle, key cap another root canal was empty. In this way, because the two needle not connected, the corresponding function have been banned, and key cap is not lost.
 
Because take key cap said only on, so there is no plug inverse problem. Key cap type jump line is divided into two needle and three needle, two needle use more convenient, more widely application, sub means has a certain function, disconnect hp g42-154ca laptop keyboard means that prohibit a function; The comparison of the three needle complex some, for instance a needle 1, 2, 3, then sub needle 1, 2 shows a kind of function, and sub 2, 3 said another function. 2. DIp type jumper DIp type jump line is also called DIp combination switch, DIp switch can not only separate the use of a push button switch said a function, more can mix several DIp switch to show more state, more features.
 
A DIp switch can be ON both sides of the button to open the two switch state, one side says open (ON), other side said shut (OFF). For the use of combination state, how many DIp switch can say 2 how many times the state of power, there are many numerical can choose, therefore, into a DIp switch control instructions must be in the form set value, otherwise you don't know so many state.
 
3. Soft jumper wire soft jumper wire and no substantial jump line, is also related to CpU set no longer use hardware jumper, but through the CMOS Setup program set up, don't need to open the case, very convenient. In computer accessories, main board, hard disk, and cd-rom, sound card in jump line, to facilitate the most complicated jump line, hard times. Second, the motherboard jumper Settings on the hp g42 laptop keyboard mainboard jump line generally includes CPU setting jumpers, CMOS clear jumpers, BIOS banned write jumper wire, etc.
 
Among them, the CPU to set jumpers most complicated, if the motherboard is old, it is necessary to set up on the mainboard kernel voltage, the frequency, frequency doubling jumpers. According to the motherboard manual and CPU frequency, set the corresponding jump line. Usually, on the mainboard corresponding CPU voltage is a set of jumper, each jump line are corresponds to a voltage value, find the right voltage value, plug in a key cap sub it, chose the voltage value.
 
Similarly, find the frequency jump line and double frequency jump line, respectively hp g56-100sa laptop keyboard set up the appropriate external frequency and frequency doubling. Note that each group jump line can only choose a jumper wire sub. The new main board more users consider comprehensive, almost all use similar soft jumper, only on the mainboard CMOS jumper still use the most primitive keycap jump line, it is more than three needle jump line. Usually, the sub needle 1, 2, said normal use motherboard CMOS, and sub 2, 3, said clear CMOS content.
 
Ban write BIOS function and not every motherboard have, generally for two needle jump line, and the concrete is short circuit to be able to write the BIOS or off to be able to write the BIOS to see motherboard manual. Some main board will let the user choose soft jumper or DIP jump line, such as asustek's P4T, if the motherboard 10 DIP switch full set OFF, it means the use of BIOS soft jumper Settings, otherwise, the choice of the DIP jump line, which switch 6 ~ 10 said external clock Settings, motherboard hp g56-100xx laptop keyboard manual there is a big table, need to control form operation, choose appropriate external clock, DIP switch 1 ~ 4 said frequency doubling, it have two of the four power of state, that is, 16 kinds of state, most can let the user choose 16 kinds of voltage value. The manual provides 14 times frequency selection, the rest of the two states in the future, not keep extended function, is the manufacturer has not publicly jump line or parameters. .

Manufacturing process, manufacturing process of the display card and hp g56-106sa laptop keyboard CPU, is to use a micron to measure the machining accuracy of. Graphics manufacturing process in 1995 years, from 0.5 micron, 0.35 micron, 0.25 micron, 0.18 micron, 0.15 micron, 0.13 micron, 0.11 micron has been developed to present the latest and nano.
 
The core frequency, refers to show the core work frequency, a bit like CPU work main frequency. Here needs to point out that is not the core frequency work on behalf of the graphics performance is strong. Such as 9600 pro core frequency up to 400 MHZ, more than 9800 pro 380 MHZ is high, but the performance is stronger than 9800 pro absolute 9600 pro. In the same level of chip, the core of high frequency is better hp g56-107sa laptop keyboard , and improve the performance of some core frequency is one of the ways card overclocking.
 
Memory usage frequency, memory card in the work frequency, with MHz (MHz) as the unit. Video memory frequency to a certain extent reflects the speed of the memory. Video memory frequency with the type of memory, performance different and different, DDR3 memory is the most widely used high-end graphics memory type. In addition, different memory can provide the memory usage frequency also difference is very big, basically have 400 MHZ, 500 MHZ, 600 MHZ, 650 MHZ, high-end products and 800 MHZ, 1200 MHZ, 1600 MHZ, or even higher. Nvidia GeForce 8700 m GT and above type of memory usage frequency has reached 800 MHZ.
 
Render pipeline, also known as the rendering pipeline, it is display chip hp g56-108sa laptop keyboard internal graphics processing signal independent parallel processing unit. The number of rendering pipeline is decided to display chip performance and grades of one of the most important parameters in the same graphics core frequency, more rendering pipeline means greater pixel fill rate and grain filling rate, from graphics rendering line number can be roughly tell graphics performance high and low class. The number of rendering pipeline is generally "pixel rendering pipeline × the number of each line texture unit quantity" to show. For example, GeForce 6800 rendering pipeline is 12 multiply one, he says it has 12 a pixel rendering pipeline, each contains 1 grain filling pipe.
 
RAMDAC, decided to refresh the discretion of the frequency, MHz for hp g56-110sl laptop keyboard unit, and display "bandwidth" meaning approximate. Its operating speed is high, the more wide frequency band, high resolution of the picture quality is better. This value determines the enough memory, graphics in support of the highest resolution and refresh rate. Such as: if you want to in the resolution of 1024 x 768 to 85 hz resolution, RAMDAC rate is at least 1024 x 768 x 85 x 1.344 ÷ 1.06 ≈ 90 MHZ. At present the mainstream graphics RAMDAC can reach 350 MHZ and 400 MHZ.
 
DirectX by Microsoft development USES a wide range of API, include Direct Graphics (Direct 3 d + Direct Draw), Direct Input, Direct Play, Direct Sound, Direct Show, Direct Setup, Direct Media Objects, and other components hp g56-113sa laptop keyboard , and is a complete set of multimedia interface scheme. It should be said that the public begin to pay close attention to mobile video card products its corresponding part DirectX has basic is the DirectX 7.0 began to dive. On the market now DirectX 7.0 related products have already out of season. The latest DirectX10, can provide a new dynamic program flow control, displacement mapping and render target, times of surface scattering, soft shadows, environment and ground shadow, global illumination and other new technical characteristics, showing a sense of reality, compared to the first all version if use "qualitative leap" to describe it too much.

1. LCD liquid crystal display (LCD) is the maintenance of notebook computer dell inspiron 630m laptop cpu cooling fan is the most delicate components, interest is accounted for about 30% of the total cost of the laptop, so the notebook computer maintenance of course should be put in the first LCD collision, avoid by all means is never in the screen picture of time, also can't use finger pointing fingers on it. Screen had better have protective film, at least to ensure the display screen can be far away from dust, fingerprints and mark. One thousand screen some dirty thing, we can try to use dry cloth to wipe, if not, can use soft cloth with some industrial alcohol or glass cleaner (not too much, as soon as the liquid into the screen inside miserably to wipe gently. Beijing IT outsourcing service network hint, had better use special design for its special screen cleaning fluid, so that we can achieve the best results. In the end to pay attention to is not on the screen, now a lot of heavy pressure of notebook computer roof use the strength of a lot of magnesium alloy and titanium alloy, but is the notebook computer after all is not used as a "sharedzilla"

2. Battery maintenance now notebook computer batteries generally has two kinds: nimh battery and lithium ion battery (due to nickel chrome battery had knocked out, here is not to say the two batteries have memory effect dell inspiron 640m laptop cpu cooling fan(only the former memory effect obviously while the latter is not obvious just and charging and discharging frequency limit. Beijing IT outsourcing service network tip first to the battery, the need for a long time of charging, the general should be continuous charging eight hours, and then every time before charging as far as possible the electricity use up (but not a little left) lithium ion battery although memory effect is not apparent, can at any time charge and discharge, but optional charge and discharge will also affect its life, should try to avoid using AC external power. When will be the best battery pulled out, or battery long time in febrile state, the life be affected. If the battery is not for a long time, please at least two months charge and discharge time, to ensure that IT is active.

3. Hard disk maintenance whether desktop or notebook computer dell inspiron 8000 series laptop cpu cooling fan hard disk is a very delicate thing. Although now hard disk has been do super earthquake, but should prevent unnecessary vibration. Because of considering the notebook computer hard disk movement problem, its seismic performance is very good, but should pay attention to mobile don't risen wildly, more can't knock fell, of course, had better not in the boot state mobile notebook computer.

4. Drive, floppy drive maintenance laptop computer dell inspiron 9200 series laptop cpu cooling fan cd-rom for volume consideration, do very thin. And CD are generally card in the axis's so try not to use inferior or irregular CD, which is very easy to damage the bald. After a period of using, want to use special CD cleaning piece cleaning bald. The floppy drive take care of oneself and desktop, do not use inferior even moldy blanks, regularly with special cleaning disk cleaning.

5. The mouse, keyboard maintenance notebook mouse generally has three kinds: trackpoint, track ball and touch panel. The track ball is very rare in the equivalent mechanical mouse ball, dirty dismounting cleaning can the trackpoint the most simple, when necessary, as long as the replacement of a special mouse cap can the touchpad is trouble replacement and maintenance are not you can do so when use must pay attention to not greasy hands to operate, more can't use sharp things above characterization, if the surface is dirty things, can use soft cloth to wipe clean with water. For notebook water this accident case, the first thing to do is to use a notebook battery off, natural dry, and then sent to the professional after-sale service center for repairs. Notebook computers dell inspiron b130 series laptop cpu cooling fan take care of oneself is (in the usual dribs and drabs of such as switch LCD to light open light off, lest cause connecting wire damage; Carry out when it is best to use special laptop bag, and remember to bag zipper buckle all button; At ordinary times and put it in a more clean place, not too cold, and not too hot. The best in the situation of power plug the notebook computer peripherals, etc. If you can in the usual use to yourself love machine, then it will prolong life
