Summary |
LAN Architectures refers to the overall design of a LAN. |
Two major components of LAN Architecture are the media access control and LAN topology. |
Media access methods dictate how a station gains access to the physical medium. |
The two primary methods for LAN’s are CSMA/CD and Token passing. CSMA/CD is found on Ethernet LAN while Token Passing LANs rely on token passing. |
Three common types of LAN architecture are Ethernet, Token passing and ArcNet. Ethernet networks, closely aligned with IEEE standard 802.3 are commonly distinguished by their cable; Thinnet, Thicknet, and Twisted-pair cable. |
A token ring network is an implementation of IEEE 802.5, the standard for the token ring networks. |
ArcNet was designed as a token passing bus architecture mapping loosely to the IEEE 802.4 standard. |
This specifies the standards for token passing bus networks using broadband cable. ArcNet however is a baseband network and can have a star or bus topology. |
