Final answer:
In a FastEthernet connection, a router typically receives data on pins 1 and 2. These pins are part of the RJ-45 connector using T568B or T568A wiring schemes which are essential for proper network functioning.
Step-by-step explanation:
In a FastEthernet connection, a router receives data on pins 1 and 2. FastEthernet, also known as 100BASE-TX, utilizes a twisted pair cable, typically Category 5 or better. In this scenario, the data transmission occurs over two pairs of wires: one pair is used for transmitting data (pins 1 and 2), while the other pair is used for receiving data (pins 3 and 6).
This standard follows the T568B and T568A wiring schemes, which are configurations for the pin layout of the eight-pin RJ-45 connectors used with twisted-pair cables in networking. Although both configurations are used, they are arranged differently and are compatible as long as both ends of the cable follow the same scheme.
It's essential for network professionals to know the correct pin usage to identify any connection issues or when creating network cables.
