Personal advantages: What are the advantages of computers?

The characteristics of the computer are:

1, the operation speed is fast. The internal operation of the computer is composed of digital logic circuits, which 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. For example, the calculation of satellite orbit, dam and 2 4-hour weather forecast. In the past, manual calculation took years and decades, but now it takes only a few days or even minutes to complete with a computer.

2, the calculation accuracy is high. The development of science and technology, especially the development of cutting-edge science and technology, requires highly accurate calculation. The reason why the missile controlled by computer can accurately hit the intended target is inseparable from the accurate calculation of the computer. The average computer can have a dozen or even dozens of significant bits (binary), and the calculation accuracy can range from a few thousandths to a few millionths, which is beyond the reach of any calculation tool.

3. Strong logical operation ability. Computers can not only calculate, but also have the function of logical operation, and can compare and judge information. The computer can save data, programs, intermediate results and final results, and automatically execute the next instruction according to the judgment result for users to call at any time. Users can design running steps and programs in advance as needed, and the computer runs in strict accordance with the steps specified in the program, and the whole process does not need manual intervention.

4. Large storage capacity. The memory of a computer has memory characteristics and can store a large amount of information. This information includes not only all kinds of data information, but also the procedures for processing these data.
