Are collisions possible in full-duplex Ethernet networks?

• A. True
• B. False
• C. Only on half-duplex networks
• D. Only in wireless networks

Answer: (B)

In full-duplex Ethernet networks, the ability to transmit and receive data simultaneously eliminates the possibility of collisions. Full-duplex operates by allowing two devices to communicate with each other at the same time, which means data can flow in both directions without interfering with one another. This is in contrast to half-duplex Ethernet, where devices can either send or receive data at one time, making them susceptible to collisions when two devices attempt to transmit simultaneously.

The design of full-duplex networks leverages dedicated channels for both send and receive signals, thus ensuring a clear and uninterrupted transmission path. This fundamental characteristic is what makes full-duplex communication efficient and collision-free. Therefore, the assertion that collisions are possible in full-duplex Ethernet networks is incorrect.
