Microcomputers with microprocessors as the core belong to the 4th generation of computers. Transistors are the characteristics of the second generation computers, integrated circuits are the characteristics of the third generation computers, vacuum tubes are the characteristics of the first generation computers, and large-scale integrated circuits are the characteristics of the fourth generation computers; and microprocessors are composed of one or a few A central processing unit composed of several large-scale integrated circuits.

The basic components of a microcomputer hardware system include CPU, memory, input devices and output devices. The microcomputer hardware system contains five important components: arithmetic unit, controller, memory, input device, and output device; and the controller and arithmetic unit together form the central processing unit (CPU). The main function of the arithmetic unit is to calculate and process data and information; the controller can be regarded as the brain and command center of the computer. It allows the various components of the computer to complete instructions in an orderly manner by integrating and analyzing relevant data and information.

The alt key on the keyboard used by microcomputers is called the "alternative shift key"; the alt key is one of the special keys of the keyboard, used in combination with other keys to indicate special operations; in Windows, it is also used alone as a menu bar used for mobile operations.

The development of microcomputers is characterized by the development of microprocessors, because microprocessors are the core of all computer activities; microprocessors can complete operations such as fetching instructions, executing instructions, and exchanging information with external memory and logic components. It is the computing control part of the microcomputer.

The arithmetic unit in a microcomputer is the core component used to perform numerical calculations and logical operations. Its functions are: 1. The arithmetic unit is used to perform numerical calculations. Through the operation of the arithmetic unit, the computer can quickly complete a large number of mathematical operations, thereby improving calculations. Efficiency and calculation accuracy; 2. The arithmetic unit is also responsible for performing logical operations. Through logical operations, the arithmetic unit can judge the input logical values and generate corresponding logical results; 3. The arithmetic unit also has the function of memory access, etc.

The shift key on a microcomputer keyboard is called the shift key. Microcomputer is a small electronic computer composed of large-scale integrated circuits. It has the characteristics of small size, high flexibility, low price and easy use.

The basic function of the microcomputer controller is to control all parts of the machine to work in a coordinated manner. The computer controller is the nerve center of the computer, commanding all parts of the machine to work in automatic coordination; under the control of the controller, the computer can automatically follow the program settings. Perform a series of operations in specified steps to complete a specific task.

The CD-ROM used in microcomputer systems with multimedia functions is a kind of "read-only optical disk memory"; ROM stands for read-only memory, and CD stands for optical disk, so CD-ROM should be a read-only optical disc memory. An external storage medium capable of storing large amounts of data. When reading data on a CD-ROM, a laser beam is used to scan the disc, and digital information is obtained based on the reflection changes of the laser on the small pits. The information on the disk is stored in spiral optical tracks.
