COMPUTER NETWORKING
Definition
A grouping of computers and peripherals connected together

themselves. Hence, a network must have at least two nodes and a medium to
connect them together so that they can send or receive information.
Networking is a convenient way of making information
accessible to anyone, anytime, and anywhere.
