EARLY COMPUTER

ENIAC

The ENIAC was the first of a versatile machine that could be used in various fields, such as weather forecasting, astronomy, etc.. It 'was designed for military purposes and was built in 1945 by John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School in America. In 1948, because of the difficulty in programming the ENIAC was changed for the registration of a computer program for the advice of Dr. John von Neumann. The disadvantages of the machine, the more irritating is that almost every day, several tubes burned half the time and make functional the day. Years, cheaper and faster computers, have begun to build, and the ENIAC was fully shutted in 1955.

CSIRAC

CSIRAC become Australia's first digital computer, and also the first computer outside the United States and Great Britain. It was designed by Trevor Pearcey and Maston Beard in 1949. It was 1000 times faster than the best mechanical calculators at that time and also the first computer in the world that can play digital music.

EDSAC

EDSAC was built by Professor Sir Maurice Wilkes of Cambridge University, England in 1949. The first video game, OXO, was written for EDSAC. 9 years later at the same university, EDSAC 2 was suggested.

Binac

Binac was designed for Northrop Aircraft Company for use in an application in the air in 1949. It was the first product of the Eckert-Mauchly Corporation Computer. Binaca ran with the help of two independent computer all sides. However, it was a clumsy and Binaca was never used for its primary purpose.

EDVAC

EDVAC was designed by John Mauchly and J. Presper Ecket and built at the Moore School at the University of Pennsylvania in the United States. It was designed for military purposes and which came into use in 1951. The main objective of the design was to address the weaknesses that have emerged in the ENIAC. Instead of ENIAC, EDVAC could work eight hours a day, without a fault. Ultimately, after BRLESC stepped forward and take his place, was low in 1962 EDVAC shutter.

SEAC

SEAC has been built in America in 1950. It 'was built by the National Bureau of Arts booth interim pending machine that uses powerful computers to be completed.

UNIVAC

UNIVAC computers were first designed by John Mauchly and J. Eckert Prespes and the first UNIVAC computer was completed in 1951 by a group called the Division of Remington Rand Univac. While all other than its creators believed that mass production of computers would be useless, UNIVAC I was advanced for trade. The UNIVAC I, the group built a series of machines begins with UNIVAC UNIVAC II and III, which are updated on the UNIVAC I, UNIVAC 9000 series.

ILLIAC

ILLIAC series, due to their speed of supercomputers have been considered at the time. All computers in this series was built at the University of Illinois at Urbana-Champaign. These computers, and the time they were built are; ORDVAC (1951), ILLIAC I (1952), ILLIAC II (1962), ILLIAC III (1966), ILLIAC IV (1976), ILLIAC V (Cesar) (1988), ILLIAC VI (under construction) and the Trusted ILLIAC (2006).

 Maniac

Manic first computer was built by Nicholas Metropolis in Los Alamos Scientific Laboratory in 1952. The difference between this machine, all other computers was that he could not exchange programs with other computers. There were two versions of The Maniac, he's crazy II (1957), and manic III (1964).

JOHNNIAC built the Rand Corporation in 1953. It 'was constantly used in 1953-1966, which has the longest life among the early computers.

 

BRLESC which was built by the Ballistic Research Laboratory U.S. Army in 1962. It was designed to take the place of the EDVAC. That has been updated with BRELESC II in 1971.
