circuit switching

Computer

A method of communications that is used in telephone systems and requires a physical transmission path—a circuit—to exist between the two devices wishing to communicate. The end-to-end path must exist before data can be sent. The only delay to which the data is subject is the propagation delay along the transmission medium (6 microseconds per 100 km for copper telephone lines). Since the path is reserved during the entire connection, any unused bandwidth is wasted. Compare message switching, packet switching, virtual circuit.

Electronics and Electrical Engineering

A technique used in digital communications that provides point-to-point connection by setting up a virtual circuit between two nodes, which remains in place throughout the conversation whether or not either node has any information to transmit. Compare packet switching.
