what are four purposes of the computer
There are four main equipment functions of a computer system: Input, Processing, Storage and Output Input: the transferring of information into a computer system-for our purposes this will be accomplished when you, the programmer, type source code at the keyboard or open a previously typed program. Processing: the manipulation and control of information within the computer system. Such manipulations are handled by the Control Unit, the Arithmetic Logic Unit and Temporary Storage. Storage: the means by which information can be permanently saved (until such time as you wish to delete it).
