Final answer:
In a FastEthernet connection, a switch typically receives data on pins 1 (white-orange) and 2 (orange). The standard pinout for 10BASE-T and 100BASE-TX includes receiving on these pins while transmitting data via pins 3 and 6.
Step-by-step explanation:
In a FastEthernet connection, a switch receives data on pins 1 and 2. FastEthernet refers to the variations of Ethernet that can carry data at rates up to 100 Mbps. In the context of the standard 10BASE-T and 100BASE-TX Ethernet, which are the most common forms of FastEthernet, data reception and transmission follow a specific pinout: data is received through pin numbers 1 (white-orange/+/data0+) and 2 (orange/-/data0-), while pins 3 (white-green/+/data1+) and 6 (green/-/data1-) are used for data transmission.
