Overview Of Networks
A basic computer network consists of a collection of hardware devices that is connected with one another so that they can communicate among themselves.
Networks are normally made up of:
Switches - A network switch forwards data packets between devices. Switches send packets directly to devices, rather than sending them to networks like a router does.
