Binary system is a numeration system based on 2 in mathematics and digital circuits, and it represents the binary system based on 2. This system is usually represented by two different symbols 0 and 1, which was discovered by Leibniz. In digital electronic circuits, binary is directly applied to the realization of logic gates, and binary is used in modern computers and computer-dependent devices.

Binary data also uses the position counting method, and its bit weight is a power based on 2. Summing by weighted expansion, the specific steps of this method are to write binary numbers into weighted coefficient expansion first, and then sum according to the addition rule of Lida decimal system.

Introduction to Computers

Computer, commonly known as computer, is a modern electronic computer for high-speed calculation, which can be used for numerical calculation, logical calculation and memory storage. It is a modern intelligent electronic device that can run according to the program and automatically process massive data at high speed. Computer is one of the most advanced scientific and technological inventions in the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality.

It consists of hardware system and software system, and a computer without any software is called bare metal. It can be divided into five categories: supercomputer, industrial control computer, network computer, personal computer and embedded computer. More advanced computers include biological computers, photonic computers and quantum computers.
