Difference between Half duplex and Full duplex

WebIf it's a hub it must be half duplex. It is hard to find a hub and virtually impossible to find a 100mb "hub". These days 10mb just doesn't cut it so hubs are really not a great solution. Managed switches that can do port mirroring aren't really all that expensive these days. Or you can build yourself a network tap if you like to roll ghetto style. WebHalf duplex means data can be relayed in only one direction at a time.Two-way transmission is possible, but the transmissions must be alternate.

"Weba hub typically operates in half duplex; there is also a security issue with hubs since the traffic is forwarded to all ports (except the source port), which makes it possible to capture all traffic on a network with a network … " - Half duplex hubs

Half duplex hubs

WebBy connecting each device directly to a port on the switch, either each port on a switch becomes its own collision domain (in the case of half-duplex links), or the possibility of collisions is eliminated entirely in the case of full-duplex links. For Gigabit Ethernet and faster, no hubs or repeaters exist and all devices require full-duplex links. WebThe forced full duplex switch has to negotiate with the hub using the auto-detect mechanismto set it up in the half duplex mode. And when the half duplex mode is set up, the communication will occur. My question now …

Any packet entering a port is repeated to the output of every other port except for the port of entry. Specifically, each bit or symbol is repeated as it flows in. A repeater hub can therefore only receive and forward at a single speed. Dual-speed hubs internally consist of two hubs with a bridge between them.
