This article will explain in detail what are the functional components of the hardware system of Feng Yiman computer. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Functional components: arithmetic unit, controller, memory, input device and output device. The arithmetic unit is the component of arithmetic and logic operation; the controller is the center of unified command and coordination of other components; the memory is the part of computer memory or temporary storage of data; the input device is the device of inputting data and information to the computer; the output device is the device of outputting the results of computer processing.

The functional components of the hardware system of Feng Yiman computer are: arithmetic unit, controller, memory, input device and output device.

The basic working principle of computer was first put forward by von Neumann, an American Hungarian scientist, in 1946. Its basic ideas can be summarized as follows:

① computer consists of arithmetic unit, controller, memory, input device and output device.

② programs and data are represented by binary numbers in the computer

The working process of a ③ computer is controlled by a stored program.

The basis that the computer can automatically complete the operation or processing process is the stored program and program control, and the principle of stored program and program control is the core of von Neumann's thought.

1. Controller

The controller is a component that analyzes the input instructions and uniformly controls each part of the computer to complete a certain task.

It is generally composed of instruction register, state register, instruction decoder, sequential circuit and control circuit.

It is a component that coordinates and directs the work of various parts of the computer. its function is to extract commands from memory in turn, generate control signals, issue instructions to other components, and direct the whole operation process.

The controller is the center of unified command and coordination of other components.

2. Arithmetic unit

Arithmetic unit, also known as arithmetic logic unit (ArithmeticLogicUnit referred to as ALU), is a component that carries out arithmetic and logic operations.

The main function of the arithmetic unit is to perform all kinds of arithmetic and logic operations and process the data.

Controller, arithmetic unit and register constitute the core of the hardware system-CentralProcessingUnit (CPU for short).

CPU is integrated into a chip with large-scale integrated circuit process and is the core equipment of computer system.

3. Memory

Memory is a part of a computer that remembers or temporarily stores data.

All the information in the computer, including the original input data.

The intermediate data after preliminary processing and the useful information completed by final processing are stored in memory.

Moreover, the various programs that direct the computer to run, that is, a series of instructions that specify how to process the input data, are also stored in memory.

Memory is divided into internal memory (referred to as memory or main memory) and external memory (referred to as external memory or auxiliary memory, such as hard disk).

4. Input equipment

The input device is the device that inputs data and information to the computer, the bridge of communication between the computer and the user or other equipment, and one of the main devices for information exchange between the user and the computer system. The task of the input device is to send data, instructions and some logo information to the computer. Keyboard, mouse, camera, scanner, stylus, handwriting board, joystick, voice input device and so on all belong to input devices (Input Device). It is a device for people or externally to interact with the computer, which is used to input the original data and the programs that process the data into the computer.

The computer can receive all kinds of data, which can be either numerical data or non-numerical data, such as graphics, images, sound, etc., which can be input to the computer through different types of input devices for storage, processing and output.

5. Output equipment

The output device (Output Device) represents the results of calculation or processing or intermediate results in various forms that can be recognized by human beings, such as numbers, symbols, letters, etc., so the input and output devices play a role in the connection between people and machines. The common ones are display, printer, plotter, image output system, voice output system, magnetic recording equipment and so on.

The display is a kind of indispensable picture and text output device of the computer, its function is to convert the digital signal into the optical signal, so that the text and graphics can be displayed on the screen; the printer is also a kind of main output device on the PC, it prints programs, data and character graphics on paper.

Console typewriters, stylus and monitors can be used as input devices as well as output devices.

Input and output devices (Iamp O) play the role of connection between people and computers, devices and computers, computers and computers.
