I would like to know what it means by half duplex and full duplex mode. I mean, what is the difference. Again, what is the implication of setting the system devices to either of the two modes with the following settings 10 Mbps full duplex, 100 Mbps half duplex, 1000 Mbps full duplex?
In half duplex communication mode, the signal can only be transmitted towards one side at a time, and the process involved two sides of communication. When a sender sends a message, it has to be received at the receiver's end, and then the receiver will decode the message and then get back to the sender. The sender and the receiver cannot communicate at the same time, one has to wait for the other to finish first.
As for the full duplex communication mode, the sender and the receiver can communicate at the same time. The sender does not wait for the receiver to finish talking before he can give a feedback, instead he can interrupt. The best example of that mode of communication is the use of a mobile phone.
