Fourth generation computers were developed after 1970 used Microprocessors on a silicon chip. A microprocessor performs all the functions in a Computer. This made computers very fast, efficient and smaJ.ler in size. The fourth generation Computers uses VLSI (Very Large Scale Integration) technology Mini Computer, Main Frame Computer, Personal Computer (PC) are the computers of this generation.
The significant distinction of the Fourth Generation is the development of large-scale integration (LSI) and very large scale integration (VLSI).
1. LSI placed several thousand transistors onto a single chip.
2. Microprocessors were introduced during this time that is used in today's computers.
3. No air-conditioning.
4. Minimal maintenance.
5. High component density.
6. Cheapest.
