Final answer:
In a FastEthernet connection, a PC receives data on pins 3 and 6. This follows the T568A or T568B wiring standards that are part of the IEEE 802.3 standard used in a 10/100BASE-T Ethernet network.
Step-by-step explanation:
In a FastEthernet connection, a PC receives data on pins 3 and 6. FastEthernet adheres to the IEEE 802.3 standard, and in a typical 10/100BASE-T Ethernet connection, data transmission utilizes twisted pair cables with RJ-45 connectors. For a direct connection, the use of T568A or T568B wiring standards ensures that pins 1 and 2 are used for transmitting data from a PC, and pins 3 and 6 are used by the PC to receive data.
It is important to be aware of this when setting up networks to ensure correct cable connections. Crossover cables were used to connect similar devices before auto-sensing ports became common, which swapped the transmit and receive pins. However, with modern devices, straight-through cables are predominantly used, and the devices manage the direction of data internally.
