Divide the history of computer development by the devices used. What are the microcomputers currently in use?

The history of computer development is divided according to the devices used. The microcomputers currently used are very large-scale integrated circuits. Microcomputers are an important branch of the fourth generation of computers; the fourth generation of electronic computers uses large-scale and ultra-large-scale integrated circuits as basic electronic components.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The history of computer development is divided by the devices used. The microcomputers currently used are ()

A. Integrated circuits

B. Transistors

C. Electron tube

D. Very large scale integrated circuit

Answer: D

Microcomputer is referred to as "microcomputer" or "microcomputer". Because it has some functions of the human brain, it is also called a "microcomputer". Microcomputer is a small electronic computer composed of large-scale integrated circuits. It is a bare metal based on a microprocessor, equipped with internal memory, input and output (I/0) interface circuits and corresponding auxiliary circuits.

There are three levels of microcomputer systems from global to local: microcomputer system, microcomputer, and microprocessor (CPU). Neither a simple microprocessor nor a simple microcomputer can work independently. Only a microcomputer system is a complete information processing system and has practical significance.

Microcomputers are characterized by small size, high flexibility, low price and easy use. Since the first generation of microcomputer IBM-PC was launched by IBM in the United States in 1981, microcomputers have rapidly entered various fields of society with their characteristics of accurate execution results, fast processing speed, high cost performance, lightness and compactness, etc., and technology has been constantly updated, and products have been rapidly replaced. , developed from a simple calculation tool into a powerful multimedia tool capable of processing numbers, symbols, text, language, graphics, images, audio, video and other information. Today's microcomputer products have made great leaps forward compared to earlier products in terms of computing speed, multimedia functions, software and hardware support, and ease of use.
