Question

Quizplus · Accepted Answer

A telephone system is a good example of a circuit-switched network because a dedicated physical circuit is established between two parties during a phone call, and the path is reserved for the entire duration of the call. This is different from a packet-switched network like the Internet, where data is broken up into packets and sent through shared paths with no dedicated circuit. The United States Postal Service and a local area network are also not examples of circuit-switched networks.
