Computer hardware mainly includes the host computer and what equipment

Computer hardware system: The host and external devices of a computer.

The host includes: a processor with main memory.

Peripherals include: input devices, output devices, auxiliary storage devices, and other devices such as network cards.

Computer hardware mainly includes the host and external equipment, and the hardware system of the computer is generally composed of external devices and the host. Peripherals are also known as peripherals, such as mice, keyboards, monitors, hard disks, etc.

With the rapid popularization of computer applications in China and the increasing application of networking and informatization, the market demand for computer peripheral equipment continues to grow, which has stimulated the formation and rapid development of China's computer peripheral equipment industry. Nowadays, some products have formed large-scale production and occupy a certain market share.

It is expected that in the next few years, China's computer peripheral equipment industry will continue to make progress in the research and development of independent core technologies, cultivating its own brands, improving product cost performance, expanding production scale, and increasing industry application solutions, and is expected to compete with international brands in some product areas.

The complete computer system is divided into two parts: hardware system and software system, and the hardware system includes five parts: combinator, controller, memory, input device and output device; Software systems include system software (computer operating systems) as well as application software.

Computer. Computer hardware systems.

Computer hardware is an important part of a computer, which consists of five important components: combinators, controllers, memory, input devices, and output devices.

1. Combinator.

The main function of combinators in computer hardware is to perform calculations and processes data and information. Combinators consist of the following parts: general registers, state registers, accumulators, and key arithmetic logic units.

Combinators can perform arithmetic calculations (addition, subtraction, multiplication and division) and logical operations (AND or NOT).

2. a controller.

Together, the controller and combinator make up the CPU (CPU). The controller can be regarded as the brain and command center of the computer, which can make the various components of the computer complete the instructions in an orderly manner by integrating and analyzing relevant data and information.

3. Memory.

As the name suggests, memory is the memory system of a computer, which is the notepad in a computer system. Unlike notepads, memory can not only store information, but also accept and read different information in a computer system. Memory is made up of main memory and secondary memory, and the main memory is commonly referred to as memory, which is divided into two parts: RAM and ROM.

Auxiliary memory is external memory, but when the computer processes the information stored externally, it must first go through the information exchange between the internal and external memory before it can be carried out.

4. Input device.

Both input and output devices are critical to human-machine interaction. The advent of input devices such as mice and keyboards has brought earth-shaking changes to computers. There are two main types of existing mice:

Optical mice and mechanical mice. Through the mouse, we can easily locate the coordinates on the computer screen, and can operate the graphics and software processing well, providing the greatest convenience for human beings. The keyboard is also a very important input device, and most of the computer's instructions are carried out through the keyboard.

The computer hardware system is mainly composed of CPU, memory, motherboard, hard disk drive, and optical disk drive.

The function of computer hardware is to input and store programs and data, and to execute programs to process the data into a usable form. Visually, a microcomputer consists of a main chassis and external devices. The main chassis mainly includes CPU, memory, motherboard, hard disk drive, optical drive, various expansion cards, cables, power supplies, etc.; Peripherals include mice, keyboards, and more.

Output and Input Devices:

A device that feeds data and information into a computer. It is the bridge between the computer and the user or other devices. Input devices are one of the main means of information exchange between users and computer systems.

The output device is the terminal equipment of the computer, which is used to receive the output display, printing, sound, control of peripheral device operation, etc. It is also to represent various calculation results data or information in the form of numbers, characters, images, sounds, etc.

The CPU, the memory, the CPU is the core of the computer, the equivalent of the human heart (but I think it is more like the brain), and all the calculations will be centralized here to be processed; Memory includes hard disks, memory, etc., and its main role is to store data.

The five major components of the computer hardware system are composed of combinators, controllers, memory, input devices, and output devices: they are components that analyze the input instructions and control each part of the computer to complete certain tasks.

Computer hardware consists of five major components: combinators, controllers, memory distribution, input devices, and output devices. The main functions of the components are as follows: When the combinator computer is running, the operation and type of operation of the combinator are determined by the controller.

HardwareGenerally speaking, the computer we see is composed of three parts: the main part (the main part), the output device (the monitor), and the input device (keyboard and mouse). And the host is the main body of the computer, and in the main chassis there is:

Motherboard, CPU, memory, power supply, graphics card, sound card, network card, hard disk, floppy drive, optical drive and other hardware.
