The host computer refers to the main body part of the computer except for the input and output devices. It is also a control box (container Mainframe) used to place the motherboard and other main components.
The inside of the computer host contains components such as the motherboard, CPU, memory, graphics card, power supply, hard disk, optical drive, etc., which together determine the performance of the computer.
In addition to the accessories in the host computer, a complete computer should also include 3 peripherals - a monitor, a mouse and a keyboard. In addition, in order to expand the functions of the computer, users can also configure the computer with auxiliary equipment such as printers, speakers, microphones, cameras, and USB flash drives.
External devices can be roughly divided into three categories:
1. Human-computer interaction equipment, such as printers, monitors, plotters, and language synthesizers.
2. Computer information storage devices, such as disks, optical disks, and tapes.
3. Machine-to-machine communication equipment, such as telephone lines that can be used to communicate between two computers, and they can be completed through a modem.
Peripherals can be simply understood as input devices and output devices. For example, the monitor is only an output device used to display computer information, and the mouse and keyboard are input devices used to input information, and they are both peripheral devices. The collective name for input, output devices and external memory in a computer system. It plays the role of transmission, transfer and storage of data and information. It is an important part of the computer system.
Peripherals refer to any device other than the host. Peripheral devices are ancillary or auxiliary devices that are connected to a computer. Peripheral devices can augment computer systems.
