Computer Generation

Development of the Computer Generation

Development of the computer from time to time may be separated by a generation of computers within a certain period of time. The computer as electronic data processing machines that can accept data (input) and then do the processing or data processing (process) which will provide useful information for the user (output) has gone through a long evolution. Separation in each generation of computers can be distinguished based on the equipment used in building a whole computer unit Up to now, according to various sources there are five generations of computers (some other sources assume that it's been entered into the computer generation of phase-six) in which every generation has its own advantages

First Generation Computers (1942 - 1959)

Before entering the decade of the first computer generation of 1942 - 1959, Dr. John V. Atanasoff at assisted by graduate student named Clifford Berry in 1937 - 1942 has created the first digital electronic computer, electronic digital computer is named Atanasoff-Berry Computer or ABC abbreviated. Beginning in the 1940s is an early milestone in the development of modern computer generation (first generation of computers), as the rapid development of computer technology in this decade thousands of computers have been built and developed to be able to produce high-speed computers that use storage media and memory. The first generation of computers is marked by the discovery of the vacuum tube as a signal amplifier with the raw material made of glass, so many have drawbacks, such as fragile, and easily distribute the heat so it requires another component that serves as a coolant to neutralize. However the first generation of computers have acquired a much faster speed because of a mechanical device capable of running / processing thousands of commands (command) at a time other than that he had used storage medium (storage) and magnetic core memory in the form of bracelets and a very small metal .

ENIAC was one of the first computer generation satau with vacuum tubes

Dr. John Mauchly and Presper Eckert in 1946 the creator of the ENIAC (Electronic Numerical Integrator and Computer) was completed with 18 800 vacuum tubes and weighs up to 30 tons. ENIAC requires a large space in one unit and 174 kilowatts of electrical power needed to operate it. In terms of the cost of this would have been very expensive, here is some kind of computer including the computer generation first

• ABC - the first electronic digital computer (1937 - 1942) created John V. Atanasoff and Clifford Benry as asistentnya.
• ENIAC - was developed by John W. Mauchly and J. Presper Eskert. Built in 1945 - 1946
• EDVAC (electronic discrete variable automatic computer) technology has been successful in reducing the use of vacuum tubes and ability is much better
• EDSAC (electronic delay storage automatic calculator) is the result of the development of the EDVAC by using mercury and vacuum tubes as data storage, by Dr. John Mauchly and Presper Eckert
• UNIVAC 1 (universal automatic calculator) is the first computer to process trade data with technologies that use mercury as a store in 1951 by Dr. John Mauchly and Presper Eckert
• IBM 709 in 1951 by John Von Neumann and Dr.. John Mauchly and Presper Eckert
• IBM 700 (1953)
• IBM 650 (1959)
