Computer is an electronic device capable of solving the problems by accepting data, performing prescribed operations on the data at very high speed and supplying the result of these operations.
In 1833 Charles Babbage (Father of modern computer science) proposed the “Analytical engine” which became the first completely automatic general-purpose digital computer. In 1944 – ENIAC (fully digital computer) by UNIV of Pennisylvania developed by Eckert and Mauchly – first electronic device – used 19000 vacuum tubes and 1500 Sq ft. In 1951 – UNIVAC 1 – Universal automatic computer – by the same people its remembered even today as to have predicted correctly, the election of President Eisenhower in 1952. Development of computers: From 1946 onwards computers can be divided into five generations, according to the Professional Website Design technologies used. First generation: 1946–1959: vacuum tubes: Speed 1000 Ns [1 nanosec=10 –9 sec]. Second generation: 1959 – 1965: transistors: 30 Ns. Third generation: 1965 – 1970: IC: 5 Ns. Forth generation: 1970 – 1985: Microprocessor: 1 Ns. Fifth generation: 1985 – to date: Super computers: VLSI (very large scale integrated circuits): 0.3 Ns Hardware: To operate a computer installation we must have a CPU and all the peripherals to support it these are the hardware of the installation of computers. Software: the programs that direct the computer and the system on which it will work |
