Networking allows various intelligent devices like computers, PDA, mobile phones to communicate with each other either through physical wires or wireless signals. This is nothing but the much used word "convergence" of technology. The software on the individual personal computers and the software on the server have to cooperate with each other to provide access to the shared resources. This is done by designing the software to use an agreed set of conventions (a "protocol") that is standardized so that multiple vendors can provide interoperable systems.
