What is computer ? It is Common Operated Machine Prepared to use for Trade Education and Research It is also called a Programmable Machine It is fully Electronical Machine and Digital History In its most basic form a computer is any device which aids humans in performing various kinds of computations or calculations. In that respect the earliest computer was the abacus, used to perform basic arithmetic operations. Every computer supports some form of input, processing, and output.
