You are always supposed to put all eight connectors in an RJ45 end, But in both cases only four wires are used. Pin 1 (white-orange), Pin 2 (orange), Pin 3 (white-green), Pin 6 (green) are the pins that are used.

Ethernet physical connectors provide circuits including the receive (RX), transmit (TX), and collision detection. When half duplex Ethernet is implemented, the TX circuit is always active at the transmitting station. When another station is transmitting, the station's RX circuit is always active. This is referred to as Shared Bandwidth. Full duplex Ethernet Switching provides a transmit-circuit connection wired directly to the receiver circuit at the other end of the connection. This two station connected environment creates a collision free situation on the circuit. Recall half duplex Ethernet has to manage the conditions for multiple transmissions on the same physical wire as they cannot occur.

There are two wires dedicated to transmitting and two dedicated to receiving. Whether it operates half or full duplex depends on the hardware it is attached to, not the cable.
