MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Segment-A segment is any portion of a network that is separated, by a switch, bridge or router, from other parts of the network. Backbone-The backbone is the main cabling of a network that all of the segments connect to.

Detailed explanation-2: -Router. Routers help transmit packets to their destinations by charting a path through the sea of interconnected networking devices using different network topologies. Routers are intelligent devices, and they store information about the networks they’re connected to.

Detailed explanation-3: -A bridge router or brouter is a network device that works as a bridge and as a router. The brouter routes packets for known protocols and simply forwards all other packets as a bridge would. Brouters operate at both the network layer for routable protocols and at the data link layer for non-routable protocols.

Detailed explanation-4: -A network bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments. This function is called network bridging.

Detailed explanation-5: -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.
