IEEE has produced several standards for LAN. These standards are collectively known as IEEE 802.
IEEE 802.3 (CSMA/CD)
IEEE 802.4 (Token Bus)
IEEE 802.5 (Token Ring).
10 Base 5 cabling is also called as Thick Ethernet. The notation 10 Base 5 means that it operates at 10 Mbps, uses baseband signaling, can support segments of up to 500 meters, and there can be 100 nodes per segment.
10 Base 2 cabling is also called as Thin Ethernet. The notation 10 Base 2 means that it also operates at 10 Mbps, uses baseband signaling, and can support segments of up to 185 meters, and each segment in turn may consist of 30 nodes.
10 Base T cabling is the most popular one because it supports the use of twisted pair cable, usually these wires are telephone company twisted pairs, since most office buildings are already wired this way, and there are normally plenty of spare parts available. The notation 10 Base T means, it operates at 10 Mbps, baseband signaling, and twisted pair cable is supported. It can support segments of length 100 m, and there can be 1024 nodes per segment.
The Ethernet networks provide shared access to nodes connected through a physical medium. These nodes form a Collision Domain. All frames sent on the medium are physically received by all receivers, however, the MAC header contains a destination address which ensures only the specified destination actually forwards the received frame to the application.
