The first generation computers were developed during 1943-1958. It used vacuum tubes as the active electronic components and was therefore very large. However some of the features are as follows-
a) They were extremely large and occupied a very large space.
b) They used vacuum tubes as memory device.
c) They were very expensive and consumed a lot of electrical power.
d) The operating speed was measured in milliseconds.
e) These computers had low level of accuracy and reliability.
f) Storage capacity was too small only 1 to 4Kb.
g) They used machine level programming language.
The examples are- UNIVAC, ENIAC, EDSAC, EDVAC, and UNIVAC.
The second generation computers were developed during 1959-1965. The invention of the transistor by three scientists of Bell Telephone Laboratories in 1947 greatly changed the development of computers. However some of the features are as follows-
a) These computers used transistor.
b) They were smaller, faster and cheaper than first generation of computer.
c) They consumed less electrical power than first generation.
d) The operating speed was measured in microseconds.
e) They were more reliable and accurate than the first generation computers.
f) They could understand high level language such as COBOL.
g) Magnetic tapes were used as secondary storage media.
The examples are – IBM 1620, IBM 1401, and CDC 3600.
The third generation computers were developed during 1966-1973. The development of Integrated Circuit (IC) signaled the beginning of the third generation computers. However some of the features are as follows-
a) These computers used integrated circuits.
b) They were small, efficient and reliable.
c) Operating systems were developed.
d) Monitors and keyboards were introduced for input and output of data.
e) Magnetic disks were used for secondary storage.
f) The operating speed was measured in nano seconds.
g) They could understand large number of high level languages.
The examples are – IBM 360, ICL -1900, and IBM 370 etc.
The fourth generation computers were developed during 1974-1990. This generation of computer is presently in use. The development of microprocessor signaled the beginning of the fourth generation of computers. However some of the features are as follows-
a) These computers use LSI and VLSI technologies.
b) Its sizes were reduced to desktop and laptop computer.
c) These computers are highly reliable and accurate.
d) They have a large memory and high functional speed.
e) The operating speed is measured in beyond picoseconds and MIPS (Million of instruction per second)
f) Magnetic disk is the common source of external storage.
g) Multiprocessing and multiprogramming OS (operating system) are used.

Computers do not have models like cars but when they invent another type they call it a new generation.
