Name: RUID: I. Quickies (20 points) A. Differentiate between time-division multiplexing and statistical multiplexing (packet switching). In time-division multiplexing, each host on the link is assigned a time slot during which to broadcast. Each host is given an equal time slot regardless of whether they broadcast or not. In statistical multiplexing, each host broadcasts when it has data to send, and when collisions occur, hosts rebroadcast according to a specific algorithm. Statistical multiplexing “wastes” less bandwidth by allowing all hosts to transmit whenever they want, instead of making them wait. B. List the 5 layers of the IP stack and give a brief description of the purpose of each.
