What are the logic devices used in the fourth generation computers?

The main logic components of the fourth generation computers use large-scale and very large-scale integrated circuits.

The main logic components of the first-generation computers used electron tubes; the main logic components of the second-generation computers used transistors; the main logic components of the third-generation computers used small and medium-sized integrated circuits: The fourth-generation computers used small and medium-sized integrated circuits. The main logic components of modern computers use large-scale and very large-scale integrated circuits.

The fourth generation electronic computer

Large-scale and super-large computers appeared in 1967 and 1977 respectively scale integrated circuit. Computers assembled from large-scale and very large-scale integrated circuits are called fourth-generation electronic computers. The American ILLIAC-IV computer is the first computer to fully use large-scale integrated circuits as logic components and memory. It marks the fourth generation of computer development. In 1975, the American Amul Company developed the 470V/6 computer, and then the Japanese Fujitsu Company produced the M-190 machine, which is a relatively representative fourth-generation computer. The University of Manchester in the UK began developing the fourth-generation aircraft in 1968. In 1974, the ICL2900 computer was successfully developed, and in 1976, the DAP series of computers was successfully developed. In 1973, Germany's Siemens, France's International Information Corporation and the Netherlands' Philips jointly established Unified Data Corporation. Jointly developed the Unidata7710 series of machines.

Electronic components

The fourth generation of electronic computers uses large-scale and ultra-large-scale integrated circuits as basic electronic components.

Features of the Fourth Generation

The fourth generation computer refers to the use of large-scale integrated circuits (LSI) and very large-scale integrated circuits (VLSI) as the main electronics since 1970. Computers made from devices. For example, the 80386 microprocessor can integrate approximately 320,000 transistors on a single chip with an area of ​​approximately 10mm × 10mm.

Another important branch of the fourth generation of computers is microprocessors and microcomputers developed based on large-scale and very large-scale integrated circuits.
