The premier invention of this century is the computer. In a short time it has affected many areas of our lives. For example. Computer helps control our automobile, act as challenging adversaries in electronic games, make possible very sophisticated medical diagnostic tools such as the computerized Axial tomography (CAT) scanner, and even act as an ideal match maker important, computer have had a tremendous impact on the way information is processed within the organizations. In fact modern management information systems would not be possible without the computer.
It has been observed that there are three elements fundamental to human activities. These elements are information, energy and materials. It has further been observed that all these elements are necessary to provide the physical thing which humans need I.e; food,clothing, shelter and transportation.
In addition to supporting physical production, however information is also the substance of all men's intellectual activities. It is basic to education, Government, literature, the product of the business and the maintenance and expansion of Man's store of knowledge. Just as the harnessing of energy brought about Industrial Revolution, so too is the attempt to harness and transform information bringing about
WHAT IS A COMPUTER?
To a layman, a computer is a data processing machine. A computer is a machine that takes in information(called data) and process it in some way. Processing is the handling, changing and storing of information. For example, when we add two numbers we are processing them in a specific way.
Also people give computer orders , they write programs to tell computer what to do. In this context, a program is a set of instruction that the computer follows when it is processing information.
Some of the programs used by the computer are stored inside the computer ,people who operate the computer never see this program. Other programs are written by the computer user. The user may have different needs, when many different users have the same needs, programs are developed and sold that may help them. For example, many offices need a programs to process payroll information. Instead of hiring a computer programmer to write a computer program offices can buy software (a program that has already been written) to use with their computers.
Computer can perform te arithmetic that is asked for in a program. Even if the formula is long or difficult or time consuming, computer follow Instruction to do the mathematics.
If you call a friend in another state, if you cash a cheque, or if you go to the library, you will probably use a computer. If you need complicated medical helps or if you run a business, the computer will help you l. The computer has become an important part of our lives, And it will become even more important in the future. What is a computer, and why is it so important? How can it be helpful in so many ways? What ideas and machine were developed to produce the computer of today?
CHARACTERISTICS OF THE COMPUTER
1. Its electronic
2. It can perform arithmetic operations
3. It can compare
4. It has internal storage and retrieval of data
5. It can execute a stored program
6. It has a choice to execution paths within a program.
WHY ARE COMPUTERS POPULAR?
Many people use computer in many different ways. What makes them so popular? How can the sane too/machine help a Banker, a Farmer, a Doctor? Several things about computers explains their popularity
1. COMPUTER CAN MANAGE HUGE AMOUNT OF INFORMATION:
Computer process great quantities of information that would otherwise be very difficult to manage or calculate. Having information available is always important, not only for educational purpose but also in the world of business.
2.COMPUTER ARE FAST:
Computer process information (often called data) so quickly that even the words to describe the amount of time it takes them to do it may be new to you. For example, one second contains on million microseconds. Or one billion nanoseconds. Information that may take days or weeks for a human being to calculate can be calculated in a nanoseconds on the computer
3.COMPUTER ARE ACCURATE:
computer do exactly what they are told to do. Sometimes that are told to do wrong thing. That is, sometimes the programmer makes a mistake when he or she write the program. Then the computer doesn't give correct ressults. If a program does not contain the right information and directions, the results will not be correct. But errors are very rarely the computers fault.
4. COMPUTERS DON'T GET BORED:
A good program can be run over and with large amounts of data. The computer may have to repeat calculations many times, it dies not get tired, bored, or frustrated with this work. It never ask for a coffee break to relieve the monotony of its work
USES OF COMPUTER:
1. In Schools
2. In Science
3. In Engineering
4. In Business
5. In the Government
6. In the Social Science
