The term Ethernet refers to the family of local-area network (LAN) products covered by the IEEE 802.3 standard that defines what is commonly known as the CSMA/CD protocol. Four data rates are currently defined for operation over optical fiber and twisted-pair cables:
- ● 10 Mbps - 10Base-T Ethernet
- ● 100 Mbps - Fast Ethernet
- ● 1,000 Mbps - Gigabit Ethernet
- ● 10,000 Mbps - 10 Gigabit Ethernet
Ethernet is currently used for approximately 85 percent of the world's LAN-connected PCs and workstations. Ethernet is the major LAN technology because of the following characteristics:
- ● Is easy to understand, implement, manage, and maintain
- ● Allows low-cost network implementations
- ● Provides extensive topological flexibility for network installation
- ● Guarantees successful interconnection and operation of standards-compliant products, regardless of manufacturer
