100BASE-T (100 Mbps)
1000BASE-T (1000 Mbps) (or 1 Gbps)
10GBASE-T (10Gbps)
also known as Fast Ethernet, is an IEEE 802.3u standard for Ethernet that provides a maximum data transfer rate of 100 megabits per second (Mbps). It uses twisted-pair cabling (specifically Category 5 or higher) and RJ-45 connectors for transmission, with the most common variant being 100BASE-TX. This standard supports both half-duplex and full-duplex modes, operating over distances up to 100 meters.
