Final answer:
The "T" in 10Base-T and 100Base-T stands for Twisted Pair, indicating the type of cabling used for Ethernet networks and reflecting the standards for 10 Mbps and 100 Mbps transmission speeds, respectively.
Step-by-step explanation:
The "T" in 10Base-T and 100Base-T standards stands for Twisted Pair, which is the type of cabling used in networking to connect different devices like computers, switches, and routers. These Ethernet cable standards are part of the IEEE 802.3 standard and define the use of twisted pair wires and signal characteristics for achieving data transmission speeds of 10 Megabits per second (Mbps) for 10Base-T and 100 Mbps for 100Base-T.
Each number in the names (10, 100) indicates the maximum transmission speed in Mbps that the network can support while Base refers to baseband signaling, implying that the cable carries baseband (single signal) transmissions.
