The human society has advanced. Our requirements have multiplied. Machines have limitations. The capacity of a machine cannot go beyond. To enable machines, like 'Computers', to work with increased efficiency, 'Computer Networks' were designed. Once a 'Computer' is part of a 'Computer Network', we can see the performance of the 'Computer' climbing up. Also, necessity is the mother of invention. To handle our ever growing list of problems, it was thought that if 'Computers' could be made to cooperate among, the capacity of these electronic machines would shoot up. Indeed this shot in capacity has resulted in increased performance. High performance of 'Computers Networks' is a result of a good teamwork among connected 'Computers'. The level of user satisfaction registers increase. We can easily say that a 'Network' of two 'Computers' is much more powerful than the power of the two same unlinked 'Compute...
