Advantages of computers

The calculation speed is fast, and the internal circuit of the computer is composed, which can complete various arithmetic operations at high speed and accurately. Today's computer systems have a computing speed of trillions per second, and microcomputers can reach more than 100 million times per second, enabling a large number of complex scientific computing problems to be solved. Calculations of satellite orbits, calculations of large dams, and 24-hour weather calculations take years or even decades, whereas in modern society, it only takes a few minutes to complete with a computer.

Desktop computers have high computing accuracy, and the development of science and technology, especially the development of cutting-edge science and technology, requires highly accurate calculations. The accuracy of a computer-controlled missile against a predetermined target is inseparable from the computer's precise calculations. Generally, computers can have more than a dozen or even dozens of significant digits, and the calculation accuracy can range from a few thousandths to a few millionths, which is beyond the reach of any calculation tool.
