The introduction of computers is said to follow that pattern. Slowly but surely, however, computers have crept into our life. The microcomputer is now widely accepted as a very efficient device for performing many types of operation, such as the display of business and other information from a data base. It is used for performing computations of varying types at high speed including professional, scientific, engineering and accounting calculations. It is employed for mathematical calculations for the classroom as well as for word processing in typing and secretarial departments.In business the computer is known to be a means increasing administrative efficiency, payroll processing, sales, etc.
Therefore the pressure on those who still are unfamiliar with computers and their use is ever greater. So almost everyone will need to become familiar with data processing and computing, particularly microcomputing, to a greater or lesser extent. No matter whether we need it in the home, office, school, college or factory, it will be almost as commonplace to use a computer as it is to drive a car.
Computers today are said to become more and more user friendly. That is they are becoming much easier to use and understand. To use a computer in the past, one had to learn computer languages such as FORTRAN (FORmula TRANslation) or COBOL (COmmon Business-Oriented Language). The learning process was slow, errors were plentiful, and the whole process was difficult for many students.
Today's computers are much easier to use. Focus in many schools is shifting away from programming computers to using them performing different types of operation.
Due to computer application, a lot of new jobs have appeared. Some of the careers in computers will involve systems analysts. Systems analysts have the challenging job of analyzing the many functions of the firm and designing a computer system to perform those functions more efficiently. First the systems analysts study how the job is now being performed. They must learn what information must be collected and processed, what output is needed, what computer capacity is needed, and the costs involved. Systems analysts must explain the system to the various computer users and tell the programmers what the system needs to do.

The greatest increase in computer jobs in the future may be for computer service technicians. During the last decades, companies were busy installing computers. Someone has to maintain and fix those computers. This is a great opportunity for someone to start his or her own service business.
Thanks to computers and the information revolution lots of professions have appeared, someone, for example, must teach people how to use computers. There are computer consultants who advise firms which computer to buy. Computer librarians keep track of all the tapes, disks, and other data storage devices. A data processing manager supervises the data processing center. Computer security specialists try to prevent computer crime. Technical writers write the manuals that tell how to use the computer. Naturally, there are also computer engineers who design computers and manufacturers that produce computers.There is a device that allows people to stay at home and work with a computer at work. It is called a modem. A modem converts data into a form that can be sent over phone lines so that one computer can talk to another.
Another major revolution is occurring in the use of computers to run machines, including robots, i. e. the use of computer-driven machines to do work formerly done by humans. Robot technology has improved dramatically in the last few years. Today, intelligent robots are being used for different purposes. Some robots can see and read using cameras. One robot, for example, detects irregularities in welded seams and corrects any mistakes. Another robot reads identifying numbers in nuclear fuel rods. The newest robots can feel the difference between an egg and a piece of steel and handle each of them accordingly. Some robots even respond to voice commands. Computers linked with robots can perform dirty, difficult, repetitive tasks faster, cheaper, and better than people.
