Duplex, Half Duplex and Simplex
Duplex, Half Duplex and Simplex are the three possibilities for the direction of data transmission.
Simplex
Simplex is data transmission in one direction only. Two directional transmission is not possible.
e.g. a radio station broadcast.
Half Duplex
Data transmission in both directions is possible, but not at the same time.
e.g. walkie talkies
Full Duplex
Data transmission is possible in both directions at the same time (simultaneously).
e.g. telephones.
