Basics Of Data Communication: Part 7
This article will explain, Introduction to LAN, MAN and MAC, IEEE Standards, LAN, Topologies in very detailed. Introduction to LAN, MAN and MAC There are two types of Network Technology: Switch Networks and Broadcast Networks. In switch network, systems are interconnected by means of point-to-point transmission lines, multiplexers and switches. In switching Networks, the transfer of packet across networks requires routing, to direct packets from source to destination, as the source and destination stations will not be connected by a single transmission link most of the cases. But in Broadcast Networks, all the system are connected to common transmission medium, which acts as a broadcast medium making routing unnecessary. Since the transmission medium is shared by all the connected systems, there is a need for additional layer, consisting of Medium Access Control (MAC) Protocol to orchestrate the transmission from various systems. The role of MAC protocol is to co-ordinate the acce
