What parts does a computer host consist of?

A computer host contains a variety of basic components that work together to power its operation. From the hard drive that stores data to the central processing unit that processes instructions, each part plays a vital role. This article is brought to you by PHP editor Banana. It will deeply explore the various components of the computer host and let everyone understand how they work together harmoniously to ensure the normal operation of the computer.

The computer host is mainly composed of: motherboard, CPU, memory, graphics card, sound card, network card, power supply, optical drive, hard disk and chassis. For example, TV cards can be installed for watching TV, capture cards can be installed for monitoring systems, etc. Now we mainly introduce the basic components that make up the host. Other components will be introduced in subsequent articles.

Motherboard:

The role of the motherboard in the computer host is to connect the various components in the computer host. The quality of the motherboard will also affect the overall performance of the computer. There are many sockets on the motherboard for connecting computer accessories. Such as CPU socket, memory socket, hard disk or optical drive IDE and SATA socket, etc. At the same time, the socket type also indicates the type of accessories that can be supported.

CPU:

CPU is the central processing unit, which can be understood as equivalent to the human brain in its image introduction, which plays a computing role. It is the main component that determines the speed of the computer.

Classification of CPUs:

1. According to manufacturers, they are mainly divided into INTEL, AMD, and domestic Loongson (currently I know only these three in China). INTEL is the first manufacturer to develop processors. With its strong research and development capabilities and overall performance, it occupies the main market of processors. As INTEL's main competitor, AMD has a very promising future in the international market with its superior cost performance and powerful graphics processing capabilities. Because the domestic Loongson started late, it lags behind in technology. Currently, many brand phone manufacturers are already using domestic VIA processors. Sales are also good.

2. According to the name: the previous computers were like 286, 386, 486, etc. I won’t go into details. In the early days, computers were basically Pentium-based. When buying a computer, you would always ask the Pentium number. . Nowadays, as hardware performance becomes more and more powerful, the names of processors are also various. INTEL processors have evolved from the Pentium series at the beginning to the current Ce Young, Ce Young D, Ce Young dual-core, PD (Pentium D), PDE (Pentium E), Core, Core 2E series (dual core), Core 2Q series (quad core) )wait. AMD's corresponding Sempron, Athlon, Athlon dual-core, Phenom triple-core, Phenom quad-core, Opteron, etc. In the past, the performance of a processor could be determined based on its main frequency. But now, with the improvement of technology, many products have lower main frequencies due to the number of cores and cache levels. So now the main frequency is not the main parameter that determines the speed of the processor. The performance can only be seen by comparing the main frequencies of the same names. When I buy, I mainly look at the price. Basically, mainstream products with higher prices must have higher performance than lower-priced products. Haha, let’s use it as a reference.

3. By pin: INTEL processor starts from 370 pins of P3 to 423 pins of early P4. Then to the 478 pins that became popular later, and now the 775 pins. AMD started from Sempron 1500+ with 462 pins, to 754 pins, and the 939 pins launched the year before last and the now mainstream AM2 (940 pins).

Memory: Random access memory refers to the program running in the computer. The space occupied when running is provided internally. The size of the memory is also a major factor in determining speed. Memory is mainly divided into SD memory, memory sticks for P2 and P3 computers, double-notch; DDR first-generation memory and now DDR2-generation memory. Among them, the number of gold fingers of SD memory is 168, the number of gold fingers of first-generation DDR memory is 184, and the number of gold fingers of second-generation memory is 240. The above refers to desktop memory. The memory of the notebook will not be detailed here.

Hard disk: The hard disk is a hard circular magnetic surface storage medium. It not only has a large storage capacity, but also is fast. It is the main storage device of the current computer. Hard drive interfaces are now mainly divided into IDE and SATA interfaces. The smallest capacity currently on the market is 160G. Since Hitachi launched 1TB (1000G) last year, major brand manufacturers have successively launched TB-level products.
