In half-duplex, communication transmission takes place from both sides, but only one direction at a time. Likewise, a railway track can operate from one direction either a train can enter or leave a railway track.
Currently, now it is moving to full duplex. One for up and second for down
half duplex data transfer both direction but only one direction at a time so railway track just a example of half duplex
As we all know that in a railway track, only one train can travel on each track. just like half duplex which we can do operations bidirectionally but only one process at a time.
Definitely a nice question.
nice question
