What are the main applications of computers at present?

Computer applications include the following:

1. Scientific calculation (or numerical calculation)? Early computers were mainly used for scientific calculation. At present, scientific calculation is still an important field of computer application, such as high-energy physics, engineering design, earthquake prediction, meteorological prediction, aerospace technology and so on.

2. Data processing (information management) uses computers to process, manage and operate any form of data, such as enterprise management, material management, report statistics, account calculation and information retrieval, mainly including data collection, conversion, grouping, organization, calculation, sorting, storage and retrieval.

3. Auxiliary Engineering Computer Aided Design, Manufacturing and Testing (CAD/CAM/CAT).

4. Production automation is to use computers to automatically detect some signals in the industrial production process, store the detected data in the computer, and then process the data as needed.

5. Artificial intelligence has developed some application systems with some human intelligence, such as computer reasoning, intelligent learning system, expert system, robot and so on.

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.

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.
