What are the Access methods used in LAN:
i. Switched access: It is used in LANs which are assigned around CBXs. Electronic switching is techniques are used to provide access.
ii. Multipleaccess: In multiple access schemes like CSMA, whenever a station gets ready for transmission, it first listens to bus to see if there is any ongoing transmission. If there is one, new transmission isn't initiated until bus becomes free. This makes sure that an ongoing transmission isn't corrupted by a new transmission.
iii. Token passing access: In this scheme, a token packet is introduced to network. This packet continues to circulate through network as long as no user accepts it. When a user works to transmit he waits for token packet to reach him and accepts token, this acceptance removes token packet from the network.
