What is the difference between 10BASE-T, 100BASE-T, and 1000BASE-T

10BASE-T is the IEEE standard that defines the requirement for sending information at 10 Mbps on unshielded twisted-pair cabling and defines various aspects of running Ethernet on this cabling.

100BASE-T is the IEEE standard that defines the requirement for sending information at 100 Mbps on unshielded twisted-pair cabling and defines various aspects of running baseband Ethernet on this cabling.

1000BASE-T (also called gigabit Ethernet) is the IEEE standard that defines the requirement for sending information at 1000 Mbps on unshielded twisted-pair cabling and defines various aspects of running baseband Ethernet on this cabling.
