What developments in computers have taken place in the fourth generation computers?

The development of IC (Integrated Circuit) like LSI (Large Scale Integration) and VLSI (Very Large Scale Integration) took place in the fourth generation computers. Due to the development of microprocessor using LSIC (Large Scale Integrated Circuits) it is possible to place computer’s central processing unit (CPU) on single chip. Magnetic and optical storage devices with capacity more than 100 GB were used as secondary memory. Fourth generation languages (4GL) were also introduced in the fourth generation computers.
