Basic of Computer

Introduction

Computers have made great inroads in our everyday life and thinking. They are put to use for all sorts of applications ranging from complex calculations in the field or front line research, engineering simulations down to teaching, printing books, and recreational games. The ease with which computers can process data, store, and retrieve it painlessly have made them inevitable in office and business environments. The areas of applications of computers are confined only by limitations on human creativity and imagination. In fact, any task, that can be carried out systematically, can be performed by a computer. Therefore, it is essential for every educated person today to know about computers, its strengths, its weaknesses, and its internal structure. And that is what we are going to explain in this chapter

What is a Computer?

A computer is an electronic device that receives input, stores or processes the input as per user instructions and provides output in the 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 the different parts of computer that enable it to carry out tasks efficiently and correctly. We will also discuss microprocessors, the brain of computers, which actually do all the assigned tasks.
