In circuit-switched networks, which statement is true?

Circuit-switched networks reserve a dedicated path between the two endpoints for the entire duration of the session, guaranteeing the channel’s bandwidth. Once a connection is established, resources along that route are set aside for that communication, providing fixed bandwidth and predictable delay. This is in contrast to packet switching, where data is sent as individual packets over shared resources with best-effort delivery and variable delay. It’s also not limited to voice traffic—circuit switching can carry different types of traffic, though it was historically used for voice. The description that two nodes have a dedicated communications channel guaranteeing full bandwidth for the session best captures how circuit switching operates.
