Fourth Generation Of Computers 1970-96

Micro Chip Technology was used in this generation.More and more transistors were integrated into a single chip.When 10 to 20 transistors were integrated this was called Small Scale Integration or SSI. When upto 100 transistors were integrated this was called Medium Scale Integration or MSI. When over 20 Million transistors were integrated this was called Large Scale Integraion of LSI.
