A communications network that uses shared facilities to route data packets from and to different users. Unlike a circuit-switched network, a packet-switched network does not set up dedicated circuits for each session.
Type of network on which each packet contends with others for data transmission. The channel is occupied only for the duration of the packet. Routers are called packet switches when they move packets along a route to its destination. In contrast, a circuit-switched network system dedicates one circuit at a time to data transmission.
A fast network technology that allows packets to take different paths through the network to get to their destination.
