Compare and contrast half duplex and full duplex

What will be an ideal response?


Half duplex is used on a medium that can carry only one signal at a time. Transmitting and
receiving simultaneously is not allowed. Only one device can send at any time. When
Ethernet ran on coaxial cable, it used half-duplex communication. When Ethernet was
upgraded to run on hubs with twisted-pair cabling, it still used half-duplex communication.
Although the cabling could have supported full duplex, the hub was still a shared medium.
Full duplex means that each end of a communications channel can send at the same time. For
example, a switch port and the connected device can send at the same time. Switches are
capable of full duplex because they consider each connection a separate communication
channel, unlike a hub, which is a shared device.
