Higher bandwidth-It can support higher bandwidth. Question Define IP? It is an unreliable and connectionless datagram protocol.
It provides no error checking and tracking. Question What do you mean by redundancy? Answer: Redundancy is the concept of sending extra bits for use in error detection.

The word Base refers to base band, as oppose to broad band.
T means twisted pair, which is the cable used for that network. Read Here: Interview Questions and Answers. Question What is the advantage of address sharing? Answer: By using address translation instead of routing, address sharing provides an inherent security benefit. Its main task is to automatically assign an IP address to devices across the network.

This is typically done in networks. If the message is sent from a source to a any of the given destination nodes. This is used a lot in Content delivery Systems where we want to get content from any server. If the message is sent to some subset of other nodes, it is called Multicasting.
