What is the exact value of 1GB in a microcomputer?

In a microcomputer, the exact value of 1GB is equal to 1GB=1024MB.

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. (Recommended study: phpstorm)

Since the first generation of microcomputer IBM-PC was launched by IBM in the United States in 1981, microcomputers have been known for their accurate execution results, fast processing speed, and high cost performance. Characteristics such as lightness and compactness have rapidly entered various fields of society, and technology has been continuously updated and products have been rapidly replaced. It has developed from a simple calculation tool to a powerful multimedia capable of processing numbers, symbols, text, language, graphics, images, audio, video and other information. tool.

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.

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.
