- Circuit Switching A connection-oriented switching technique where a dedicated communication path (circuit) is established between the source and destination before data transmission. Once established, this path remains dedicated to the connection. Examples include traditional telephone networks. - Packet Switching A connectionless or connection-oriented technique where data is broken into packets, and each packet is routed independently across the network. Paths are not dedicated and are shared among multiple users. Examples include the internet. - Simultaneous Connections In circuit switching, each connection requires its own dedicated path to ensure quality of service and prevent interference.
