A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.
Conventionally, a computer consists of at least one processing element, typically a central processing unit(CPU) 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. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.
The first electronic digital computers were developed between 1940 and 1945. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). In this eramechanical analog computers were used for military applications.
Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Simple computers are small enough to fit into mobile devices, and mobile computers can be powered by smallbatteries. Personal computers in their various forms areicons 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 robotsare the most numerous.
From Wikipedia.com:
A computer is a machine that manipulates data according to a set of instructions.
A "computer" is any entity that "computes" or calculates, i.e. that performs logical or mathematical calculations using data provided (input).
The modern electronic computer is a device that is able to process and retain information when programmed, and which operates under the control of a set of instructions that is stored in its memory. The actual device will usually consist of a central processing unit (CPU) connected to several data input, storage, and output devices.
A computer accepts data from an input device and processes it into useful information which it displays on its output device(s).
