Computers can be divided into

according to the form of processing data, they can be divided into digital computers, Analog computer, Hybrid computer. This is classified according to the principles of computers.

1. Digital computer

Digital electronic computer is the mainstream in the electronic computer industry in the world today. What it processes internally is a signal called a symbol signal or a digital signal. electrical signal. Its main feature is "discrete", and there cannot be a third symbol between two adjacent symbols. Due to this difference in signal processing, its composition and performance are superior to analog electronic computers.

2. Analog computer

An analog computer is a computer that uses a continuously changing analog quantity as the object of operation based on the principle of similarity. Analog computers use electronic circuits as their basic computing components. It consists of computing components, control components, question setting boards, input and output devices, etc.

The solution using the similarity principle includes the concept of simulation, so it is called an analog computer. It is based on parallel computing and has fast calculation speed. It appropriately combines arithmetic units with fixed functions, so the program is relatively simple, but the flexibility of problem-solving is relatively poor.

3. Hybrid computer

Hybrid electronic computer, referred to as hybrid computer. Mainly used for high-precision and high-speed simulation tests.

The main characteristics of hybrid electronic computers are: in specific application fields, it takes advantage of both the high speed of analog computers and the high precision of digital computers. The entire system uses the support of software to make it It is versatile and easy to use within a certain range, but the system is expensive.

Hybrid Computer Digital Analog Hybrid computer is designed by combining the advantages of digital computers and analog computers. It can handle both digital and analog quantities. This kind of computer has a complex structure and is difficult to design.

The above is the detailed content of Computers can be divided into. For more information, please follow other related articles on the PHP Chinese website!
