Circuit switching v. packet switching.

Circuit switching v. packet switching.
Circuit switching and packet switching represent two fundamentally different ways of making use of network resources. In a circuit-switched network a single reliable connection is established and maintained between communicating parties for the life of their exchange. In contrast, packet-switched networks divide data into packets, each of which can flow down many different network paths.
