Packet-switched network compared with a circuit-switched network In a packet-switched network, data is broken up into smaller units (“packets”) to be transferred, while circuit-switched networks transmit data as one unit.

A circuit-switched network is a technology used for landline telephones and data networks where two endpoints are connected by a single physical path with a fixed bandwidth.

　　When did circuit-switched networks start operating? Circuit-switched networks started operating with the first telephone switch in New Haven, Connecticut, in 1878.

　　What are the advantages of circuit-switched networks? Circuit-switched networks minimize transmission delays and guarantee a steady bandwidth, especially for long-duration connections.

　　Who were the engineers that devised alternatives to circuit-switched networks? Paul Baran of the RAND Corporation and Donald Davies at the British National Physical Laboratory devised alternatives to circuit-switched networks, leading to the development of packet switching.

　　What is packet switching? Packet switching is a technology where signals are broken into smaller blocks of information (packets) that are transmitted and reassembled, improving speed and efficiency compared with circuit-switched networks.

　　circuit-switched network, technology used for landline telephones and data networks where two endpoints are connected by a single physical path with a fixed bandwidth. Since the 1960s such networks have increasingly been replaced with packet switching, a newer and more efficient alternative better suited to computer technology. Circuit switching has been used since the first telephone switch started operating in New Haven, Connecticut, in 1878. Every phone had a circuit connecting it physically to a telephone switch. In the early decades of circuit-switched networks, a third person—a telephone operator—typically acted as a go-between for two phone lines to be connected. ...(100 of 823 words)
