This article mainly introduces what is the basis of efficient computing power in computers. It has certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let Xiaobian take you to understand it together.

Computer has efficient computing power is based on advanced electronic devices, the electronic devices used to manufacture computers are large-scale integrated circuits and ultra-large-scale integrated circuits; computers are composed of hardware systems and software systems.

Advanced electronic devices are the basis of computers 'efficient computing power. The electronic devices used to make computers today are large scale integrated circuits and very large scale integrated circuits.

A computer is composed of two parts: hardware system and software system.

The hardware units of traditional computer systems can be generally divided into input unit, output unit, arithmetic logic unit, control unit and memory unit, among which arithmetic logic unit and control unit are collectively referred to as central processing unit (CPU).

Generation 4: Large-scale integrated circuit computers (1970-present)

In terms of hardware, logic elements are large scale and very large scale integrated circuits (LSI and VLSI). Database management system, network management system and object-oriented language appeared in software. The world's first microprocessor was born in Silicon Valley in 1971, opening a new era of microcomputers. The application fields are gradually moving from scientific calculation, business management and process control to family.

Due to the development of integration technology, the integration of semiconductor chips is higher, each chip can accommodate tens of thousands or even millions of transistors, and can concentrate the arithmetic and controller on one chip, thus appearing microprocessor, and can be assembled into a microcomputer with microprocessor and large-scale, ultra-large-scale integrated circuit, which is what we often call microcomputer or PC. Microcomputers are small, cheap and easy to use, but their functions and computing speeds have reached or even exceeded those of the past. On the other hand, the use of large-scale, ultra-large-scale integrated circuit manufacturing of various logic chips, has been made into a small volume, but the calculation speed of up to 100 million or even billions of giant computers. After successfully developing the Galaxy I supercomputer with 100 million operations per second in 1983, China successfully developed the Galaxy II universal parallel supercomputer with 1 billion operations per second in 1993. This period also produced a new generation of programming languages, database management systems and network software.

With the changes of physical components and devices, not only the computer host has undergone upgrading, but its external equipment is also constantly changing. For example, external memory, from the initial cathode ray display tube to the development of magnetic core, drum, and later developed into a general purpose disk, there is now a smaller volume, larger capacity, faster read-only optical disk (CD-ROM).

Thank you for reading this article carefully. I hope that Xiaobian's article "What is the basis for efficient computing power in computers" will be helpful to everyone. At the same time, I hope that everyone will support you more, pay attention to the industry information channel, and more relevant knowledge is waiting for you to learn!
