What electronic components are used in modern computers? Many novices are not very clear about this. In order to help you solve this problem, the following small series will explain it in detail for everyone. Those who have this need can come to learn. I hope you can gain something.

The electronic components used in modern computers are "large scale and very large scale integrated circuits"; hardware, logic components use large scale and very large scale integrated circuits; software has appeared database management systems, network management systems and object-oriented languages.

The electronic components used in modern computers are "large-scale and ultra-large-scale integrated circuits."

Today's computer is the fourth generation (1971-present) computer, mainly using large-scale, ultra-large-scale integrated circuits as components.

Large Scale Integrated Circuits (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).
