'Computer Evolution Essay\r'

'?Explain the growing of data processor describing the technologies employ in various genesiss. The evolution of information processing systems started way brook in the late 1930s. Binary arithmetic is at the core of the computers of all times. History of computers dates back to the founding of a mechanical adding elevator car in 1642. Abacus, an early computing tool, ruse of logarithm by John Napier and the invention of slide rules by William Oughtred were significant events in the evolution of computers.\r\nEvolution of computer engineering science can be divided into 5 generations. First generation computer consisted of void tubes and they were used from 1943-1958. ENIAC (Electronic Numerical Integrator and Calculator) computer is an example of first generation computer. mo generation (1959-1965) computer consisted of transistors i. e. vacuum tubes were replaced by transistors. Thus the size of the computer got trim considerably. Third generation (1966-1973) compute r consisted of co-ordinated circuits (IC) i.\r\ne. numerous transistors in hit te chip. A single IC has many transistors, registers and capacitors built on a single thin slice of silicon. With the invention of microprocessor (1971), quaternate generation of computer evolution started and read day computers be also reason in the fourth generation. The fifth generation computers are under development. They are deprivation to be based on principles of imitative intelligence and natural language recognition.\r\nDevelopers are aiming at computers capable of organizing themselves. The evolution of computer continues. Generation Duration Memory thingmabob First (1943-1958) Vacuum tubes Second (1959-1965) electronic transistor Third (1966-1973) LSI (Large Scale Integration) IC fourth part (1974-1990) VLSI (Very large Scale Integration) Microprocessor. Fifth (1990 onwards) Biochips (concept of AI) put back: Time period and its device used in evolution of computer.\r\n'
