Fourth generation computers (1975 onwards)

• The microchip technology was introduced in this generation of computers.
• With the advancement in IC technology, LSI (Large Scale Integration) chips were developed.
• It was possible to integrate over 30,000 or more components on to single LSI chip. After LSI, the VSLI (Very Large Scale Integration) was developed and the development of microprocessor possible.
• It is expected that more than one million components will be integrated on a single chip of VLSI.
• Using VLSI technology, the entire CPU is designed on a single silicon chip.
• The use of microprocessor as CPU introduced another class of components called the Microcomputers.
• Thus fourth-generation may be called Microcomputer generation.
• IBM introduced its personal computer for use in 1981.

Advantages:-

The advantages of fourth-generation as compared to previous generation computers are:-

• Smaller in size.

• Production cost is very low.

• Very reliable.

• Hardwire failure is negligible.

• Easily problem because of their small size.

• Totally general purpose.

• Air conditioning is not compulsory.

• Very high internal & external storage capacity.

• Used advanced input & output devices such as optical readers, laser printers, CD-ROM/DVD-ROM devices etc.

Disadvantages:-

The main disadvantages of fourth-generation computers are:-

• Highly sophisticated technology required for the manufacture of microprocessor chips.
