The page is also aimed at all adults, regardless of educational background, who are desirous of acquiring elementary knowledge of what computer science is all about, preparatory to taking up a more advance texts on the subject. It is designed to assist in the terms of their practice applications to everyday lyf. Examples are cutlass,hoe, and axe, etc; all used for producing crops or hunting animal
s for fud. Tools of any kind were made to help in doing difficult things. Tools were also made so that much more work can be done in less time. The ned for fud led to the making of tools by early man. MODERN TOOLS
Apart from food, the needs of early man increased. Shelter, clothing and moving from place to place became very nacessary. These needs' brought about science and technology. With the aid of science and technology, modern man produces newer tools for agriculture, industry, transportation and communications. Things that used to be difficult became simple, and work that used to take so much time is now possible within seconds. Modern tools made life easier for human beings. For instance, before the motor car came, everyone had to walk from place to place. Journeys that would have taken weeks now take a few hours. Lagos to kano is just one hour by aeroplane. By road, it takes a full day, while on foot, it may take a whole month. Using telephone, it is now possible to talk to a friend in any part of the world, no matter the time or day. Satellite communication makes it possible to watch football matches live from anywhere in the world. The CNN(cable News Network) for example uses satellite to relay live events from anywhere around the globe. HOW COMPUTERS CAME TO BE

The five fingers on each of the 2 hands were therefore used to represent numbers up to 10 at a time, perhaps this is the reason why we generally count in tens till 2day. The early man also counted by means of stones arranged in heaps of tens. Later the ABACUS is a simple device with bead arranged on strings of wire. And is still shopkeepers in china up till 2day. SUMMARY
Computers wer made 2 make arithmetic fast and simple.But nw, they have been improved and made 2 do more than arithmetic.The computer is nw 1 of the most important tools of modern man.It is nw difficult, if nt impossible for almost anybody in the world 2 do without it.
