numerical calculation

The application of computer
The application of computer has penetrated into every field of society,Mobile Application is changing people's work, study and life, promote social development. Baconian rise can be divided into the following several aspects:
1 Scientific Computing ( numerical )
Scientific computing, also known as numerical calculation. The computer is the beginning for scientific research and engineering design experienced a high number of mathematical problems in the numerical calculation and the development of computational tools. With the further development of modern science and technology, the numerical calculation in the modern scientific research to improve the status, in the frontiers of science, appear particularly important. For example, the satellite trajectory calculation, seismic intensity calculation, rocket, the spacecraft 's research and design are inseparable from the computer calculation.
In industry, agriculture and human society in various fields, the computer application has achieved many breakthroughs, even every day we tune in to watch the weather forecast are inseparable from the computer science and computing.
The 2 data processing ( information processing )
In scientific research and project technology, will get a large number of original data, including a large number of pictures, text, sound and other information processing of data collection, classification, sorting, storage, transmission, calculation, tabulation and other operations. At present computer information processing applications are very common, such as personnel management, inventory management, financial management, book information management, business data exchange, information retrieval, such as economic management.
Information processing has become the main task of contemporary computer. Is a cornerstone of modern management. According to statistic, the whole world computer for data processing computer application workload accounted for more than 80%, greatly improving the work efficiency, improve the level of management.
3 automatic control
Automatic control is through the computer in a process for automatic operation, it does not need manual intervention, according to predetermined goals and a predetermined state of process control. Process control refers to the operation of real-time data acquisition, detection, treatment and judge, according to the best value to adjust the process. It is widely used in the operation of complex iron and steel enterprises, petrochemical industry, pharmaceutical industry and other production. The use of computer automatic control can improve the control accuracy, improve work efficiency, product quality, reduce cost, shorten production cycle.
Computer automatic control in the defense and aerospace fields play a decisive role, for example, unmanned aircraft, missiles, satellites and spacecraft, aircraft control,Digital Marketing is relying on the computer realization. Can be said that the computer is a modern national defense and aerospace fields of central nervous system.
