A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. 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 can change the
