In a FastEthernet connection, which pins are used by a switch to receive data?

In a FastEthernet connection, the switch uses pins 1 and 2 to receive data. These specific pins are part of the eight pins in an RJ-45 connector, which is commonly used in Ethernet cables. In a standard wiring scheme for 10BASE-T and 100BASE-TX Ethernet, pins 1 and 2 are assigned to transmit data from one device to another, while pins 3 and 6 are typically used for receiving data.

Understanding this pin configuration is crucial for anyone working with networking because correct wiring ensures that devices can communicate effectively over the network. The configuration follows the TIA/EIA-568 standard, which specifies the arrangement of pins in Ethernet connections to provide data transmission in a reliable manner.

Given this context, it is clear that pins 1 and 2 are essential for establishing a proper data receive pathway in typical FastEthernet connections.
