A computer is a general purpose maneuver that can be programmed to carry out a set of arithmetic or logical operations. Since a sequence of operations can be bear witnessily changed, the computer can solve more than one conformation of problem.Conventionally, a computer consists of at least one bear upon element, typically a central processing unit of measurement and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on stored information. circumferential devices allow information to be retrieved from an external source, and the result of operations salvage and retrieved.In World War II, mechanical analog computers were routined for specialized military applications. During this time the first electronic digital computers were developed. Originally they were the sizing of a large room, consuming as much power as several hundred modern personal computers .M odern computers based on integrated circuits be millions to billions of times more capable than the early machines, and subscribe to a fraction of the space. Simple computers are sharp enough to convulsion into mobile devices, and mobile computers can be powered by small batteries. Personal computers in their various forms are icons of the Information Age and are what most people think of as computers. However, the embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous.History of compute Etymology The first recorded use of the word computer was in 1613 in a book called The yong mans gleanings by English writer Richard Braithwait I haue read the truest computer of Times, and the best Arithmetician that euer breathed, and he... ...e working at Bell Labs in November 1937, Stibitz invented and construct a relay-based calculator he dubbed the Model K, which was the first to use binary circuits to pe rform an arithmetic operation. Later models added greater sophistication including difficult arithmetic and programmability.The AtanasoffBerry Computer was the worlds first electronic digital computer, albeit non programmable. Atanasoff is considered to be one of the fathers of the computer. Conceived in 1937 by Iowa State College physics prof John Atanasoff, and built with the assistance of graduate student Clifford Berry, the machine was not programmable, being designed only to solve systems of linear equations. The computer did rent parallel computation. A 1973 court ruling in a unmingled dispute found that the patent for the 1946 ENIAC computer derived from the AtanasoffBerry Computer.The fir
