APPLICATION AND USE OF COMPUTERS
in general, human beings can do whatever computers can do but computers can do it with much greater speed and accuracy. this is in spite of the fact that computers preform all their calculations and operations  one step at a time. for example ,a human being can take a list of 10 numbers and find their sum all in one operation by listing the numbers one over the other and adding them column. a computer, on the other hand, can add numbers only two at a time, so adding this same list of numbers will take nine actual addition steps. of course, the fact that the computer requires only a nanosecond or less per step, makes up for this apparent inefficiency.

a computer is faster and more accurate then people but unlike most people it has to be given a complete set of instruction that till it exactly what to do at each step of operation. Thai set of instruction, called a program, is prepared by one or more persons for each job, the computer has to do. these programs are placed in the computer's memory unit in binary-coded from, with each instruction having a unique code. the computer takes these instruction codes from the memory one at a time and performs the operation called for by this code.
computers have found their way into application areas that were not feasible 20 years ago. the rapid increase in the number and variety of computer application has made them significant part of our lives. the following sections present examples from some of the major areas of application
