 COMPUTER

  Computer is a device that accepts data in a digital format and manipulates it to give an output. The output is determined by the instructions (program) given to the system. The computer may have a fixed in built program or may be fed different programs depending on the required output.

 Modern computers also have the ability to store the programs and the data it is working with. The earliest computers were mechanical calculators, which were then replaced by the vacuum tube systems. The invention of the transistor and integrated circuits made widespread computing a reality.
