FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Circuit switching requires a dedicated physical connection between the sending and receiving devices.

Detailed explanation-2: -The correct answer is option 2, i.e. Circuit Switching. Circuit switching is a switching method in which a dedicated communication path in physical form between two nodes within a network is established, maintained and terminated for each communication session.

Detailed explanation-3: -Circuit switching is when a dedicated channel or circuit needs to be established before users can speak to each other on a call. A channel used in circuit switching is kept reserved at all times and is used once the two users communicate. Circuit switching connections are classified as half-duplex or full-duplex.

Detailed explanation-4: -Packet switching is a WAN switching method in which network devices share a single point-to-point link to transport packets from a source to a destination across a carrier network. Statistical multiplexing is used to enable devices to share these circuits.

Detailed explanation-5: -Circuit Switching. Circuit switching is a switching technique that establishes a dedicated path between sender and receiver. In the Circuit Switching Technique, once the connection is established then the dedicated path will remain to exist until the connection is terminated.
