Nowadays, DIY is very popular in the computer industry, and some DIY experts frequently make moves to make suggestions for their relatives and friends. However, there are often such experts. Whether computers are configured for Zhang San, Li Si or Wang Er, they all choose roughly the same hardware configuration, regardless of their different needs.

In fact, due to the differences in industry needs and personal hobbies, the computer application scope of different users is very different. Therefore, the emphasis of hardware configuration should be different to truly meet people's needs, which is more important for our DIY computers. Below, the author tries to give several examples to illustrate the points that need attention when DIY computers are used for different purposes.

I. Small servers

Now the network can be said to be everywhere. Companies, internet cafes and even families have set up small local area networks, so DIY of servers has been put on the agenda. Generally speaking, the configuration of the server should consider the stability and speed of the system.

1, Motherboard: As the core component of the whole network, the server needs stable performance and can work continuously for a long time. A machine that crashes frequently can't bear the heavy responsibility anyway. The stability of a server is closely related to the quality of the motherboard. Therefore, when DIY servers are used, we must choose motherboards with good brand, good performance and high quality, such as those of ASUS and Gigabyte.

2.CPU: As a server of a small network, the general division of labor should not be too detailed. All mail services, file services and programs run on one server, so the performance of the server is directly related to the running speed of the whole network, and CPU, as the core component of the server, is the most important. As there is no dedicated server model for P4 at present, we can choose P4 CPU whose main frequency is over 2.0G as the core of small network server. Of course, we can also choose two or more PCs as needed.

3. Memory: Because the server needs to process multiple programs in parallel, the demand for memory is naturally much higher than that of personal computers. Moreover, the network operating system such as windows 2000 Server itself has a high demand for computer memory. At present, the servers that meet the general requirements should have more than 5 12M memory.

4. Disk system: Personally, this is another core of the whole server. Because network users frequently visit the server and run programs, the speed of the disk system is a key part of the overall performance of the server. According to the different purposes of the server, it can also be subdivided as follows:

For high-speed requirements, such as video-on-demand servers, you can choose SCSI interface to configure dual SCSI hard disks and establish RAID 0 mode disk array. Because SCSI hard disk can reach 65,438+00,000 rpm, its performance is much higher than that of IDE interface hard disk, and SCSI interface has priority over IDE interface in data transmission and resource occupation. RAID 0 mode disk array embodies the principle of speed first, which can greatly improve the speed of disk system. Because RAID 0 mode can't protect the security of important data well, if users have a high demand for data security, they can add another hard disk to form a RAID 3 mode disk array to protect data security to the greatest extent.

Speed requirements are general, such as general homepage publishing and mail server. For this kind of users, I suggest buying a SCSI interface hard disk with SCSI control card. First, the performance of SCSI hard disk is much better than IDE interface. Secondly, lay a foundation for future upgrades without wasting existing investment.

There is no requirement for speed, such as a general network proxy server. For ordinary users, I also suggest buying multiple IDE interface hard disks and setting up RAID systems in different modes as needed. Although the one-time investment is a little more, it is still of great benefit to the improvement of system performance. Don't save trouble, just get a 7200 rpm IDE interface hard disk like a normal desktop. Why is it called a server?

5. Finally, it is worth noting the chassis, because most servers work continuously for 24 hours, and there are many internal components, and the heat generated by the CPU is very large, plus the heat emitted by the SCSI high-speed hard disk, which makes the temperature in the chassis rise linearly. If the heat dissipation performance of the selected chassis is poor, the internal temperature of the chassis will be too high, which will cause the system to slow down the CPU running speed, thus affecting the system performance. Therefore, we must pay attention to ventilation in the choice of server chassis, try to buy a larger chassis, and if possible, we can also buy a brand-new all-aluminum chassis.

The above are some parts that should be paid attention to when introducing DIY server. As far as the server is concerned, its display performance and audio performance are insignificant, so you can freely choose the graphics card, sound card and monitor, and even some servers are not equipped with sound cards and monitors.

Second, computers are used as game machines.

At present, many friends buy computers mainly for playing games. Because game software, especially those large 3D games, has strict requirements on computer performance, the overall requirements for DIY game computers are relatively high. Pay special attention to the display performance and CPU processing ability when using DIY game computers.

1, graphics card: Half the performance of a game computer is on the graphics card. Choosing a powerful and excellent graphics card can give you a head start in large 3D games (such as Delta). In addition, it is best to have video output when choosing a graphics card, so that the video signal can be connected to the home TV. Is it cool to play video games with a 29-inch color TV? Asus V8200 deluxe edition, ASUS V8200,

2.CPU: As large-scale games generally enter the 3D era, the requirements for computer CPU are getting higher and higher. You can choose different types of CPU according to your favorite game types. For example, players who like large 3D games must choose P4, and other types such as puzzle and RPG players can choose Celeron or AMD.

3, sound effects: Because many games now use the latest audio technology, such as surround sound effects, environmental sound effects, and even many games are Dolby certified (exaggerated! ), so if you want to get the best sound effect, don't believe that these so-called 6. 1 channel sound cards are integrated on the motherboard and adopt the performance of the latest technologies such as SRS. Their effects are often not very good. You can configure innovative sound cards such as SB Live and Lee Tae 6X sound, which will give you a surprise.

4. Monitor: The faster the scene changes in the game, the higher the response speed of the monitor. But now many players have bought LCD, which is a very inappropriate configuration. 3000 yuan LCD investment is enough for you to buy a good CRT. We can buy a 65,438+07-inch highlight display with the latest Tellon technology.

In addition to the above components, other components such as hard disk, memory, chassis, optical drive, etc. You can buy it according to the popular configuration on the market, don't care too much.

3d animation design

Now computers have become the art of making money for many friends, such as designing 3D animations and making decorative renderings. These computers have higher requirements for 3D display ability of graphics card, computing power of CPU and memory:

1, CPU: Because this kind of computer needs to perform a lot of numerical operations, it requires extremely high CPU. Celeron or AMD can hardly shoulder this heavy responsibility except for L2 cache. You must choose P4 processor to add vitality to your excellent ideas.

2, graphics card: Also due to the need for a large number of 3D operations, the requirements for computer graphics cards are also very high. If you have enough money, you can buy a special graphics card. They generally have professional 3D engines, which can greatly improve the 3D processing ability of graphics cards and save time when you make animations and images, and most of them generally choose graphics cards above the current mainstream processing chips, otherwise the long-term helpless waiting at work is really worrying. Professional graphics cards can be selected from 3D labs Wildcat 62 10 and Wildcat 6 1 10, and general graphics cards can be selected from V8200 Deluxe and Lee Tae A250 LETD myVIVO.

3. Memory: 3D operation will also take up a lot of memory space, and image software such as PHOTOSHOP also needs a lot of memory space when working. If the memory is insufficient, the system will use hard disk to simulate memory, and the speed of hard disk and memory is very different. You will feel sad when the computer doesn't respond to the clatter of the hard disk, so this kind of computer must be equipped with enough memory, and memory above 5 12M is their first choice.

4. Display: This kind of users also have higher requirements for the display, especially for image processing, and have higher requirements for color reproduction of the display. It is recommended to buy a professional flat panel monitor. This kind of monitor has undergone special image processing and three-dimensional design optimization, and can obtain excellent visual effects. 19 or the color display on a large screen of more than 20 inches can reach the resolution of 1600 or even higher. Here you are.

5. Mouse: It is particularly noteworthy that friends engaged in 3D production and image processing must buy an excellent mouse. Ordinary mice can't be well grasped and positioned in drawing and other operations because of their low accuracy, which will affect your play, while those excellent mice with high resolution and excellent accuracy can make you get twice the result with half the effort. For example, Microsoft's trackball explorer optical forefinger shark and Logitech's infinite rotating mink will definitely make you handy.

In the past, the choice of hard disk of this kind of computer was also very important. Nowadays, most of the hard disks are 7200 rpm high-speed hard disks with 2M cache, which has already met their needs, or you can buy a hard disk with 8 cache, or even a hard disk with SCSI interface, which can better meet your needs. As for small objects such as sound cards, speakers and CD-ROMs, it doesn't matter. You can choose whatever you want.

Fourth, use the Internet.

Now more and more friends have joined the Internet addiction group, so what should we pay special attention to when using the Internet? This is the monitor and memory, etc.

1, display: This is the first component. I think friends who surf the internet often surf the internet for hours, which is very harmful to the eyes of the monitor for a long time. Therefore, when purchasing monitors, I suggest that friends with conditions try to buy LCD color monitors, because most LCD color monitors have low radiation and little harm to eyes. If you choose CRT for economic reasons, you must also choose those certified low-emission products. You know, eyes are the windows to our hearts. If they are damaged, it will be a lifetime thing. Recently, the price of LCD has plummeted, so friends who match the machine should hurry up!

2. Memory: All friends who surf the Internet have had this experience. After opening one browser window after another, the resources of the computer system drop rapidly, which leads to the slower and slower running speed of the computer. The key is insufficient memory resources, which greatly reduces the performance of the system. Therefore, computers specially used for surfing the Internet can be equipped with large-capacity memory. At present, 128M is the basic configuration, and 256M or higher capacity memory can be properly configured.

3. Modems and network cards: There are more and more friends accessing broadband networks now. It is very important to choose a good network card, which can greatly improve your network speed and stability. Now there are many cheap old ISA interface network cards, most of which do not support plug and play. It is recommended not to buy it. PCI network cards of brands such as 3COM are better choices. Of course, there are still many friends who drive cats to surf the Internet. For them, the quality of modem is more critical, because the signal transmission of telephone line is more fragile than broadband. If you use a modem with poor performance, the network will be disconnected and disconnected. Domestic cats such as Shida and Zhifu should be your first choice.

In addition, the choice of CPU is irrelevant, P4, Celeron and AMD can meet your needs; Motherboard, video card and sound card are not so important, even those integrated motherboards are good ways.

Five, multimedia computer

Many families buy computers for multimedia appreciation, so what should these friends pay attention to when purchasing machines?

1, graphics card: Graphics card is the core component of multimedia computer, which is very important for image processing, MPEG decoding and video input and output. Pay special attention to the chipset and interface of the graphics card when purchasing it.

2. Sound card: At present, many motherboards have integrated AC97 sound cards, but you can't expect these integrated sound cards to have much effect. I suggest you buy other high-end sound cards, such as SB Live series, which will make your field what is the real sound of nature.

3. Speaker: Even the best sound card should be played with a speaker. Nowadays, active computer speakers can be seen everywhere, and many of them can be counted as font sizes. Many speakers claim to adopt the latest technology, and surround sound can be achieved with three or two speakers, or even completely replace the 5. 1 speaker. Don't believe these lies naively, only you have really appreciated 5. 1 even 6.65438+. If you have money, consider the innovative DDT3500 Digital. If not, domestic rambler S5. 1 is also an ideal choice.

4.DVD drive: For multimedia computers, DVD drive is a standard configuration, because optical discs are not enough to enjoy high-quality multimedia effects. Only the pictures and sound effects of DVD are the ideal media for appreciation. I suggest you pay attention to the area code setting of DVD when buying DVD drive. Nowadays, many DVD drives have area codes, but it doesn't matter if you buy a DVD drive with a lock code. Because many of these discs can be decoded, even if most of the DVD discs on the market now are regional numbers, it will not affect your appreciation of DVD blockbusters in the future.

5. Monitor: Never choose LCD on the monitor of multimedia computer. This guy's screen refresh rate is low, which is easy to cause tailing and is not suitable for multimedia display. Of course, the best CRT is always used. Nowadays, most traditional CRT has entered the era of highlighting, which is of great help in displaying multimedia images.

In addition to these things mentioned above, there are some components such as CPU, motherboard, hard disk, etc. You can meet your needs by referring to the current popular configuration.

Above, the author mainly introduces several computers with different application ranges and chooses different configurations. In fact, computers, like all of us, have their own unique characteristics according to their application scope, work needs and personal preferences. You must not follow suit. Everyone makes the same computer. Therefore, when we do DIY, we should prioritize according to our own work priorities and personal preferences, choose accessories suitable for our own needs, highlight our own personality and characteristics, and show our charm, so as to save money and improve system performance. This is the real meaning of our DIY computer.
