These are telecommunications and networking terms.
Duplex or Full Duplex means that both ends of the circuit can both send and receive at the same time.
With Half Duplex, only one end can send at a time.
With Simplex, communication can flow in only one direction.

Not a guru, but I've got this. A half duplex system can only either receive or transmit at one time. A full duplex system will allow for both receiving and transmitting at the same time. Example: When you speak, and the other guy speaks at the same time, on a half duplex system, neither of you will hear the other, because both radios are in 'transmit' mode. On a full duplex system, your radio would be transmitting your speech while broadcasting the other guys' transmission as well. I'm not too sure about radios, but I know with speakerphones, full duplex is the way to go. Otherwise, ambient noise will cause the speaker/radio to switch to transmit mode rather than receiving mode, and results in choppy conversations. Full duplex, I think, is well worth the extra cost. Just my two cents.

these describes communication channels, refering to 2 parties scenario.
Simplix means that there is a dedicated path to each direction of flow between the 2 parties. you can send and receive simultaniosly but it requires double chanels.the voice channel in GSM mobile system (and most of the wireless communication) is of that type since there is one frequency to send and another to receive). Rs 232C fo data communication is of this type too.
Duplex means One channel for both directions.
Half duplex allows one direction to be on the channel each time. also you cant transmit and receive simoultanously. you have to wait the channel to be freed just like push to talk button used in walkie talkie. Most LAN and WLAN technologies use this type of communication since there is only one sender each time although there would be more than one listener.
full duplex allows flow in both directions so you can send and receive on the same channel. subscribed telephone line of this type since both terminals puts there signal on single line (2 wire only).
