What are the main application fields of computers?

Computer applications mainly include: numerical calculation, data processing, automatic control and aided design.

1, numerical calculation

Computers are widely used in the calculation of science and engineering technology, which is a basic aspect of computer application, and we are familiar with it. Such as: the calculation of satellite orbit, the calculation of various parameters of missile launch, the calculation of seismic strength of buildings, etc.

2. Data processing

It is called data processing to record, sort out and calculate data in time by computer and process it into the form required by people. Compared with numerical calculation, the main characteristics of data processing are more raw data, large processing capacity and strong timeliness, but the calculation formula is not complicated. Today, with the popularization of computer applications, computers are no longer just tools for scientific calculation.

3. Automatic control

Automatic control is also an important aspect of computer application. In the production process, automatic control by computer can greatly improve the quantity and quality of products, improve labor productivity, improve people's working conditions, save the consumption of raw materials and reduce production costs.

4. Aided design

Computer-aided design (CAD) is a practical technology for designing with the help of computers. Using computer-aided design process to realize automation or semi-automation can not only greatly shorten the design cycle, speed up the upgrading of products, reduce production costs and save manpower and material resources, but also play an important role in ensuring products.

Advantages of computers:

1, fast operation speed: the internal circuit of the computer can complete various arithmetic operations at high speed and accurately. At present, the operation speed of computer system has reached trillions of times per second, and the microcomputer can reach more than 100 million times per second, which can solve a large number of complex scientific calculation problems.

2. High calculation accuracy: the development of science and technology, especially the development of cutting-edge science and technology, requires very high calculation accuracy. The reason why the missile controlled by computer can accurately hit the intended target is inseparable from the accurate calculation of the computer.
