Third Generation ( 1964- 1982 )

Invention of  technology  of integrated circuits created computers  of third  generation. In  several  logical  gates  are fabricated on a single piece of silicon. Size of computers was further reduced computing power increased cost reduced in this  generation technology  of changed from SSI (small scale integration less than 12 logical gates on a single chip) to  MSI ( medium  scale integration more than 100 gates on a  single  chip) and then to LSI ( large scale integration more than 100 gates on a single  chip. IBM  360  PDP -8 , PDP 11,  CRAY -1, VAX were the  name of few computer of  third  generation.
