The term “Computer Network “ is used to mean an interconnected collection of computers. Two computers are said to be interconnected if they are able to exchange information. The connection can be wired or wireless. A large computer with remote printers and terminals is not a network.Distribution or exchange of information is very important for any group activity to work efficiently and effectively. This is best achieved by networking.
