Second Generation Computers Computer(used transisters to process data) Store, transmit and process data 

1964-1979

Third Generation Computers Computers(used intergrated circuits (ICs) to process data) Store, transmit and process data with better storage and increased speed of processing

1979-1989

Fourth Generation Computers Computer(used VLSI-very large scale intergrated circuits to process data) store, transmit and process data with better storage and increased speed of processing than 3G computers

1990-present

Fifth Generation Computers Computers(Use advanced VLSI in the name of microprocessor to processor data) Store, Transmit and process data with better storage and increased speed of processing, small in size and emit less heat and consumes less power. Faster than 4G computers and also portable.
