Computer Evolution Essay

? inform the phylogeny of information processing system describing the technologies used in different contemporariess. The evolution of computers started counselling back in the late 1930s. Binary arithmetic is at the result of the computers of all times. History of computers dates back to the invention of a mechanical adding appliance in 1642. Abacus, an early computing tool, invention of logarithm by hind end Napier and the invention of slide rules by William Oughtred were significant events in the evolution of computers.phylogenesis of computer technology can be divided into five generations. outgrowth generation computer consisted of emptiness tubes and they were used from 1943-1958. ENIAC (Electronic Numerical Integrator and Calculator) computer is an example of first generation computer. Second generation (1959-1965) computer consisted of transistors i. e. vacuum tubes were replaced by transistors. Thus the size of the computer got reduced considerably. Third generatio n (1966-1973) computer consisted of integrated circuits (IC) i.e. many transistors in angiotensin converting enzyme silicon chip. A single IC has many transistors, registers and capacitors built on a single thin slice of silicon. With the invention of microprocessor (1971), one-fourth generation of computer evolution started and present day computers are also categorized in the fourth generation. The fifth generation computers are under development. They are going to be based on principles of artificial intelligence and natural language recognition.Developers are aiming at computers capable of organizing themselves. The evolution of computer continues. Generation Duration reposition device First (1943-1958) Vacuum tubes Second (1959-1965) Transistor Third (1966-1973) LSI (Large plateful Integration) IC Fourth (1974-1990) VLSI (Very large Scale Integration) Microprocessor. Fifth (1990 onwards) Biochips (concept of AI) Table fourth dimension period and its device used in evoluti on of computer.
