MULTICASTING:
The answer to above problem is multicasting. It is the normal form of broadcasting. It acts like broadcasting however it does not broadcast frames automatically to the CPU.
The interface hardware is programmed in advance to receive some frames that have multicast address as the destination address. If an application needs to receive some frames then it program the interface hardware to receive an additional set of addresses.
The interface hardware frame then starts accepting three kinds of frames:
MULTICAST ADDRESSING:
We take an example of computers executing an audio program. We see that they may accept audio frames if the interface are programmed to received them and the other devices that are not running that audio programs will not waste sources
Question: (a) Distinguish between Flow Control and Congestion Control. (b) Explain clearly how a URL is resolved by a computer. (c) List one application that uses TCP
When a switch is said to be congested? It is possible that a switch receives packets faster than the shared link can accommodate and keeps in its memory, for an extended period
What is a Associative Memory
PROBLEM WITH BROADCASTING: There are some issues with the broadcast. For each broadcast frame on the network every computer uses computational sources and places the data into
Ping and Traceroute are used by ICMP for Testing. Destination Unreachable messages are obtained by a router when it does not have a route to the network.
