Generations of Computer

Generations of Computer Points : Generations of computer, Describe generations of computer? How many generations of computer describe each of generation Generations of computer After the introduction of ENTAC (Electronic Numerical Integrator the computer) in 1943 by S.P Eckert & T.W Mauchly, The process of development of computer is a continues process. The development of computer could be categorized into following five generation, as compare to previous generation new technology were as well as in the performance with new and more applications. 1st Generation This generation can be considered by 1946, in this generation. binary system and concept of presenter program was introduced were constructed by vacuum tubes. ENIAC (Electronic numerical Integrator and calculator) in 1946, EDSAC (Electronic Delay Storage Automatic calculator) in 1951 were also first generation computers, First generation computer are IBM-650, IBM-705, IBM-709 etc 2nd Generation In this period computers became much in size, faster, more reliable, and much greater in processing capacities compared to first generation. Built in error detecting devices were installed 3rd Generation The era of this generation is only five years old i. e 1965 to 1970 (I’C) Integrated circuits are introduced in this generation. The new solid state circuitry increased the speed of computer, arithmetic and logic operation ere begins performed in micro second and even in nano seconds, required low voltage of electricity. More easy high level programming Languages were -introduced. IBM-360 and Honeywell 200 were famous computers. 3rd Generation The era of this generation is only five years old i. e 1965 to 1970 (I’C) Integrated circuits are introduced in this generation.

Easier high level programming Languages were induced. IBM-360 and Honeywell 200 were famous computers 4th Generation The duration of fourth generation between 1971 - 1981. In 1971 powerful processor chip INTEL 8008 was introduced, 8080 INTEL processor was first, which used in PC. Many advanced input output devices are also developed in this generation. This generation based on (SSI) scale integration, and were with more storage capacity and processing speed. XT, A 286,36486, IBM AS-400 is famous computers.
