Who invented the computer?

The inventor of the computer is john von neumann.

Computer, commonly known as computer, is an 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.

The main features of the computer are as follows:

1, fast folding operation.

At present, the operation speed of computer system has reached trillions of times per second, and the microcomputer can reach hundreds of millions of times per second, which has solved a lot of complicated scientific calculation problems. For example, the calculation of satellite orbit, dam, 24-hour weather forecast and so on. 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 folding 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. Folding has the ability of logical judgment.

With the increase of computer storage capacity, more and more information can be stored and memorized. Computers can not only calculate, but also save data, programs, intermediate results and final results for users to call at any time; You can also perform arithmetic and logical operations on various information (such as video, language, text, graphics, images, music, etc.). ) through coding technology, even reasoning and proof.

4. Folding has automatic control capability.

The internal operation of the computer is automatically controlled according to people's pre-programmed programs. Users design running steps and programs in advance according to the needs of solving problems, and the computer runs in strict accordance with the steps specified in the programs. The whole process is carried out automatically, without manual intervention, and the expected effect of users is achieved.
