The host includes:

1. Motherboard

Computer chassis motherboard, also called mainboard, systemboard or motherboard (motherboard); it is divided into two types: commercial motherboard and industrial motherboard. It is installed in the chassis and is one of the most basic and important components of the microcomputer. The motherboard is generally a rectangular circuit board, on which are installed the main circuit systems that make up the computer. Generally, there are BIOS chips, I/O control chips, keyboard and panel control switch interfaces, indicator light connectors, expansion slots, motherboards and plug-in cards. DC power supply connectors and other components.

2. Central Processing Unit

The Central Processing Unit (CPU) is a very large-scale integrated circuit and is the computing core (Core) and control core (Control) of a computer. Unit). Its function is mainly to interpret computer instructions and process data in computer software.

The central processing unit mainly includes arithmetic unit (arithmetic logic unit, ALU, Arithmetic Logic Unit), controller and cache memory (Cache), as well as the data (Data), control and status that realize the connection between them. Bus. It, together with internal memory (Memory) and input/output (I/O) devices, are collectively known as the three core components of electronic computers.

3. Memory

One of the important components in the computer, it is a bridge for communication with the CPU. All programs in the computer run in the memory, so the performance of the memory has a great impact on the computer. Memory is also called internal memory and main memory. Its function is to temporarily store operation data in the CPU and exchange data with external memories such as hard disks.

As long as the computer is running, the CPU will transfer the data that needs to be calculated into the memory for calculation. When the calculation is completed, the CPU will transmit the results. The operation of the memory also determines the stable operation of the computer. Memory is composed of memory chips, circuit boards, gold fingers and other parts.

4. Hard drive

As a storage device, it has been playing an indispensable role since the birth of the computer. To a certain extent, the performance of the computer only affects the speed of computing data, while the task of the storage device is to ensure that all types of computing data survive.

5. Graphics card

is one of the most basic components of a personal computer. Its purpose is to convert the display information required by the computer system to drive the display and provide progressive or interlaced scanning signals to the display. , controlling the correct display of the monitor, is an important component connecting the monitor and the personal computer motherboard, and is one of the important devices for "human-machine dialogue".
