Computers are an obvious technology that reach into peoples lives. Computers answer telephones, retrieve information instantly, read and answers letters, and make
mathematical computations in much less time than a person can. However, how do
people react as the use of the computer increases in their daily lives? There is a big difference between talking to a human being about a mistake on a bill and trying to tell a computer. A computer does not treat people in a human way. After all, it is onlya machine. A person who learns to use any machine can benefit from its service. The same is true for the computer. The investment of time and patience that a person
makes in learning how to use a computer pays off many times.
