Which Ethernet standard utilizes pins 1 and 2 for transmitting data?

The correct answer identifies the Ethernet standard that uses pins 1 and 2 for transmitting data. In the context of 10BASE-T, which operates at a speed of 10 Mbps over twisted-pair cabling, pins 1 and 2 are designated for transmitting data. This standard uses two pairs of wires in the Ethernet cable, where one pair is used for transmission (pins 1 and 2) and the other pair is reserved for receiving data (pins 3 and 6). Understanding this pin assignment is essential for network cabling and ensuring proper connection and data transmission between devices on a Local Area Network (LAN). The 10BASE-T standard, introduced in the early 1990s, created a foundation for later Ethernet standards, which continue to leverage similar principles for data communication over twisted-pair cabling. In contrast, other standards like 100BASE-T and 1000BASE-T utilize all four pairs of wires for data transmission, thereby increasing their capacity. While 10BASE-2 is a coaxial cable standard and does not involve twisted pairs, it operates quite differently from the mentioned standards and hence doesn't apply to this query regarding pin utilization.
