Half Duplex

Half Duplex

In telecommunications, a system that allows transmission between two endpoints, but not simultaneously. For example, if two people have walkie talkies, each may speak to the other, but the signal will not transmit if both try to speak at the same time. This contrasts with a full duplex, in which information may be transmitted both ways at the same time.

As a result, they blocked the exchange of auto-sensing information, making it necessary to manually configure the hub, switch, or router port to either full or half duplex. In the best case, this required time-consuming intervention at the management console (or removing the cover to configure dip switches).
