    Fundamentals of Computer A computer is an electronic device that receives input, stores or processes the input as per user instructions and provides output in desired format. Computers have become an integral part of our lives because they can accomplish easy tasks repeatedly without getting bored and complex ones repeatedly without committing errors. In this tutorial we will discuss in detail about the different parts of computer that enable it to carry out tasks efficiently and correctly. We will also discuss about microprocessors, the brain of computers, which actually do all the assigned tasks. The term 'Computer' is derived from the Latin word 'Computar' which means to calculate.  * C = Commonly  * O = Oriented  * M = Machine  * P = Properly  * U = Used for  * T = Training  * E = Education  * R = Research A) Types of Computers: 1 Classes by purpose 2 Classes by function 3 Classes by usage 1 Classes by purpose 1.1 ...
