Detailed explanation-1: -Expert-Verified Answer c. The packet transfer delay between a pair of nodes is more or less constant. The method in which data is transferred to a network in the forms of packet is called packet switching. The data is broken into several small pieces to ensure efficiency in data transfer rate.
Detailed explanation-2: -Each router examines and sends each IP packet individually-this is called packet switching. If the network changes, due to congestion or faults, routers can use an alternative interfaces to reach a destination.
Detailed explanation-3: -In packet switching networks, routing is the higher-level decision making that directs network packets from their source toward their destination through intermediate network nodes by specific packet forwarding mechanisms. Packet forwarding is the transit of network packets from one network interface to another.
Detailed explanation-4: -A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection.
