Circuit switching is a communication method where a dedicated communication path, or circuit, is established between two devices before data transmission begins. The circuit remains dedicated to the communication for the duration of the session, and no other devices can use it while the session is in progress.

Circuit switching is a method of implementing a telecommunications network in which two network nodes establish a dedicated communications channel (circuit) through the network before the nodes may communicate. The circuit guarantees the full bandwidth of the channel and remains connected for the duration of the communication session.

Circuit switching is a switching method where an end-to-end path is created between two stations within a network before starting the data transfer. Circuit switching has three phases: Circuit establishment, Transferring the data and circuit disconnect.

Circuit Switching is a dedicated connection path between the sending and receiving devices. The dedicated route is a connected series of connections between the switching nodes. A traditional mobile network, where a dedicated route is established between the caller and the called party for the span of a mobile call, is termed as circuit switching.

As a method of data transmission, circuit switching is relatively straightforward. It involves setting up specific design circuits or lines for a network trajectory. With this particular trajectory established, the sender is free to deliver a series of data pieces to recipient. This is in contrast to another method called packet switching.
