Microcomputers are referred to as "microcomputers" and "microcomputers". Because they have certain functions of the human brain, they are also called "microcomputers". 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.

Microcomputers are characterized by their small size, flexibility, low price, and ease of use. (Recommended learning: PHP Video Tutorial)

Integrating a microcomputer on a chip constitutes a single chip microcomputer (Single Chip Microcomputer). A system consisting of a microcomputer equipped with corresponding peripherals (such as printers) and other dedicated circuits, power supplies, panels, racks, and sufficient software is called a microcomputer system (commonly known as a computer).

Microcomputer is referred to as microcomputer, commonly known as computer, and its accurate name should be microcomputer system. It can be simply defined as: an entity composed of necessary external devices and software configured on the basis of a microcomputer hardware system.

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.

A complete microcomputer system includes two parts: hardware system and software system. The hardware system consists of arithmetic units, controllers, memories (including memory, external memory and cache), and various input and output devices, and works in an "instruction-driven" manner.

Software systems can be divided into system software and application software. System software refers to software that manages, monitors and maintains computer resources (including hardware and software). It mainly includes: operating system, various language processing programs, database management system and various tool software, etc. The operating system is the core of the system software. Only through the operating system can users complete various operations on the computer. Application software is a computer program compiled for a certain application purpose, such as word processing software, graphics and image processing software, network communication software, financial management software, CAD software, various program packages, etc.

The development of microcomputers is usually based on the development of microprocessor chips, CPUs. When a new type of CPU is successfully developed, the corresponding software and hardware supporting products will be launched within one year, thereby further improving the performance of the microcomputer system. In this way, a new generation of microcomputers will be formed in only two or three years. product. Intel Corporation of the United States has always been in a dominant position as a manufacturer of microprocessors. In fact, the history of microcomputers so far is also the history of the development of Intel microprocessors.

The Windows operating system is a single-user multi-tasking system. After more than ten years of development, it has developed from Windows 3.1 to Windows NT, Windows 2000 and Windows XP. It is an important part of microcomputers. One of the widely used operating systems.

Linux is an operating system whose original code is open to the public. It has been adopted by more and more users and is a strong competitor of the Windows operating system.
