This article mainly introduces the logic components used in the third generation computer, which are introduced in great detail in the article and have certain reference value. Interested friends must read it!

The logic elements used in the third generation of computers are: medium and small scale integrated circuits. The third generation computer refers to the third generation integrated circuit computer, characterized by small and medium-sized integrated circuits to constitute the main functional components of the computer, the main memory using semiconductor memory; logic elements using small and medium-sized integrated circuits (MSI, SSI).

The logic elements used in the third generation of computers are: medium and small scale integrated circuits.

The third generation computer, the third generation integrated circuit computer (1964-1971). It is characterized by small and medium-sized integrated circuits (each chip integrates less than 1,000 logic gates)(Western writing SSI, MSI) to form the main functional components of the computer; the main memory adopts semiconductor memory. The calculation speed can reach hundreds of thousands to millions of basic operations per second. In terms of software, the operating system is getting better and better.

In the third generation computer, in terms of hardware, logic elements use medium and small scale integrated circuits (MSI, SSI), and the main memory still uses magnetic cores. In software, time-sharing operating systems and structured, large-scale programming methods have emerged. It is characterized by faster speeds (generally millions to tens of millions of times per second), significantly improved reliability, further price reduction, and product generalization, serialization, and standardization. Application areas began to move into word processing and graphics and image processing.

LSI (Large-Scale Integration) is a logic circuit formed by concentrating a plurality of electronic components on a substrate of a few square millimeters. The basic electronic components of third-generation computers are small-scale integrated circuits with a few to a dozen electronic elements (logic gates) on each substrate and medium-scale integrated circuits with dozens of elements on each chip.

The further development of computer software technology, especially the gradual maturity of operating systems, is a prominent feature of the third generation of computers. The development of multiprocessor, virtual memory system and user-oriented application software greatly enriches computer software resources. In order to make full use of existing software and solve the problem of software compatibility, a series of computers have appeared. The most influential was the IBM-360 computer series developed by IBM.

Another feature of this period was the use of minicomputers. DEC company developed PDP-8 machine, PDP-11 series machine and later VAX-11 series machine, etc., have played a great role in the promotion of computers. It is characterized in that transistors are used instead of electronic tubes; magnetic cores are used in large quantities as internal memories, magnetic disks and tapes are used as external memories; the volume is reduced, the power consumption is reduced, the operation speed is increased to hundreds of thousands of basic operations per second, and the memory capacity is expanded to hundreds of thousands of words.

Computer language development to the third generation, entered the "human-oriented" language stage. Third generation languages are also known as "high-level languages." A high-level language is a programming language that is close to what people are used to. It allows the calculation program to be written in English. The operation symbols and operation formulas used in the program are almost the same as the mathematical formulas we use in daily life. High-level language is easy to learn, strong versatility, written out of the program is relatively short, easy to promote and exchange, is an ideal programming language. High-level languages developed between the mid-1950s and the 1970s, and some popular high-level languages have been adopted by most computer manufacturers and fixed in computer memory, such as BASIC (there are no fewer than 128 different BASIC languages in use, of course, their basic characteristics are the same). In addition to BASIC, there are more than 250 high-level languages such as FORTRAN, COBOL, C, DL/I, PASCAC, ADA, etc.
