Final answer:
Ethernet, a common LAN technology, historically used Manchester encoding for data transmission, where bits are represented by voltage transitions to ensure synchronization.
Step-by-step explanation:
True. Ethernet, a standard technology used to interconnect devices in local area networks (LANs), indeed historically used Manchester encoding for signaling.
Manchester encoding is a method of encoding clock and data signals into a single self-synchronizing data stream; it ensures that there is a transition at the middle of each bit, aiding clock recovery.
This means that a logical '0' is represented by a transition from high to low in the middle of the bit period, and a logical '1' is represented by a transition from low to high. Current Ethernet standards have evolved to use more advanced encoding schemes like 8B/10B, but classic Ethernet used Manchester encoding.
