1. What are the five generations of computers?
A. Generation of Computers

      Five generation of computers

1)                  1^st generation [1951-58]: - 1^st generation of computers uses the vacuum tubes, low memory of the computer and slow processing.

2)                  2^nd generation [1958-64]: - vacuum tubes replaced with transistors. To improve the computer memory and speed.

3)                  3^rd generation [1964-71]: - Transistors replaced with IC (Instigated circuits) to improve the computer memory and speed and install computer languages.

4)                  4^th Generation [1971-82]: - IC replaced with LSIC (Large scale instigated circuits).

5)                  5^th Generation [1982-onwords]: - LSIC replaced with VLSIC (very large scale instigated circuits). To improve the computer memory and speed.
