The Ethernet specification is the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. It uses the CSMA/CA access method to handle simultaneous demands.
Ethernet supports data rates of 10 Mbps, Fast Ethernet supports 100 Mbps, and Gigabit Ethernet supports 1 Gbps. Its cables are classified as “XbaseY”, where X is the data rate in Mbps and Y is the category of cabling. The original cable was 10base5 (Thicknet or “Yellow Cable”). Some others are 10base2 (Cheapernet), 10baseT (Twisted Pair), and 100baseT (Fast Ethernet). The latter two are commonly supplied using CAT5 cabling with
