The display system of the PC is composed of two parts: the display control interface and the monitor. The display system is an electronic system that provides visual information. Its main application areas are: 1. Status monitoring of traffic control communication systems; 2. Display of various non-directly visible images; 3. Human-computer interaction equipment for electronic computers.

What does the display system of a PC consist of and the monitor?
A display system is an electronic system that provides visual information. According to different applications, the display system uses one or more display devices, one or more display devices, provides visual information required by a single person or a group of people, and receives signals from different electronic devices or systems. It generally needs to be equipped with appropriate Input devices to enable human-machine contact and necessary recording equipment for later review.
The main application areas of the display system are:
① Traffic control, industrial process control and status monitoring of military command and control communication systems.
② Display various non-visible light or non-directly visible images. Such as used to display images in X-ray, ultraviolet, infrared, remote sensing and medical electronic equipment.
③Human-computer interaction equipment (or terminal equipment) of electronic computers. Used for printing and typesetting, animation production, computer-aided design, etc. This system has an electron beam tube monitor for the computer to output information and a keyboard for the operator to input information to the computer.
④Target display in radar, navigation, electronic reconnaissance and other equipment.

The development of computers is mainly divided according to the electronic components that make up the computer. It is divided into four stages, namely, the electron tube stage, the transistor stage, the integrated circuit stage, the large-scale and VLSI stage (now).
The first generation (1946-1957) electron tube computer, the main logic component used in the computer is the electron tube, also known as the electron tube era. The main memory uses a magnetic drum core, and the external memory uses magnetic tape. In terms of software, programs are written in machine language and assembly language. The characteristics of computers during this period are: large size, low computing speed (generally thousands to tens of thousands of operations per second), high cost, poor reliability, and small memory capacity.
The second generation (1958-1970) transistor computer, the main logic component used in the computer is the transistor. Main storage uses magnetic cores, and external storage uses tapes and disks. In terms of software, management programs began to be used, and later operating systems and high-level programming languages appeared. During this period, the application of computers expanded to data processing, automatic control, etc. The running speed of computers has increased to hundreds of thousands of times per second, the size has been greatly reduced, and the reliability and memory capacity have also been greatly improved.
The third generation (1963-1970) integrated circuit computer. Computers in this period used small and medium-sized integrated circuits to replace discrete components, used semiconductor memory to replace magnetic core memory, and used magnetic disks for external memory. In terms of software, the operating system has been further improved and the number of high-level languages has increased. The running speed of computers has also increased to hundreds of thousands to millions of times per second, the reliability and storage capacity have been further improved, and there are many types of external devices. Computers and communications are closely integrated and widely used in scientific computing, data processing, transaction management, industrial control and other fields.
The fourth generation (after 1971) large-scale and very large-scale integrated circuit computers. The main logic components of computers in this period were large-scale and ultra-large-scale integrated circuits, which is generally called the era of large-scale integrated circuits. The memory uses semiconductor memory, and the external memory uses large-capacity soft and hard disks, and optical disks have begun to be introduced. On the software side, operating systems are constantly being developed and improved. The development of computers has entered an era characterized by computer networks. The running speed of computers can reach tens of millions to trillions of times per second. The storage capacity and reliability of computers have been greatly improved, and their functions are more complete. During this period, in addition to small, medium and mainframe computers, computer types began to develop into two aspects: supercomputers and microcomputers (personal computers). The birth of microcomputers was marked by the emergence of microprocessors (CPUs) in 1971. Its main The structure is the arithmetic unit and controller, which enables computers to enter various fields of human society.
