How to buy a computer to see the configuration

When buying a computer, we usually look at the configuration of the computer, so for the layman, buy a computer how to look at the configuration? How to look at the configuration of the computer? Here are some relevant information, take a look at it!

Computer configuration generally from two aspects, first, the hardware; the second is the software

Hardware aspects

1, CPU, this mainly depends on the frequency and level two cache, the higher the frequency, two-level cache, the faster the future CPU will have three levels of cache, four level cache, etc., affect the response speed.

2, memory, memory access speed depends on the interface, the number of particles and storage size (including the memory of the interface, such as: sdram133,ddr233,ddr2-533,ddr3-800), in general, the larger the memory, processing data capacity, the faster the speed.

3, the main board, or processing chips, such as: Notebook i965 than i945 chip processing capacity is stronger, i945 than i910 chip in the processing of data more powerful, and so on.

4, hard disk, hard disk in the daily use, consider less, but there are some effects, first of all, the speed of the hard disk (points: High-speed hard drives and low-speed hard drives, high-speed hard drives are generally used in large servers, such as: 10000 rpm, 15000 rpm; Low speed hard drives are used in general computers, including laptops), Desktop computers generally use a 7200 rpm, notebook computer generally use 5400 rpm, this is mainly considering the power dissipation and cooling reasons.

Hard disk speed due to different interface, the rate is different, in general, the IDE and SATA (that is, often said serial port) interface, the earlier hard disk is the IDE interface, in contrast, access speed than the SATA interface slower.

Hard disk also with the development of the market, the cache from the previous 2M rose to 8M or greater, like the CPU, the larger the cache, faster.

5, Graphics card: This is the operation of large program software response speed has a direct connection, such as the operation of Cad2007,3dstudio, 3DMAX and other graphics software. In addition to the hardware level of the graphics card, there is a "shared memory" technology, and the general self-video memory

The difference between the chips is that the "shared memory" technology needs to read the memory from RAM to handle the needs of the corresponding program. Or some people call it: dynamic memory. This kind of technology is used more in the notebook computer.

6, the power supply, this as long as the power is sufficient and stability is good, also OK.

7, Monitor: Monitor and motherboard interface also have an impact, but people generally do not care too much (please refer to the Display equipment related technical information).

Software aspects

1, operating system: A simple example to illustrate: the same configuration of the computer, running the original Windows 98 is certainly faster than running the original Windows XP, and the original XP is certainly faster than running the original Windows Vista, which means that the same configuration, The larger the system resources the software occupies, the slower the speed, and the faster the reverse.

Also, the original English version of the operating system running English program than running the Chinese version of the program stability and speed are related.

Therefore, this particular emphasis is on the original system, that is, no streamlined system. Similarly, streamlined Windows XP is generally faster than the original XP, because it has a noticeable increase in speed by streamlining some of the less frequently used programs and consuming less system resources.

2, software (including hardware) can be properly optimized to fit the user, such as: General Office, configuration of the general computer, installed a compact version of the XP and compact version of Office 2003 is enough to deal with the day-to-day use of. However, if you are a graphic designer, you need a professional configuration, especially for graphics, so upgrading software: Microsoft DirectX 9.0 or above is necessary. It is used for playing games alone.
