Half-duplex - is the mode typically used in a walkie-talkie. Units usually broadcast and receive on the same frequency - so one party must wait until the other has finished transmitting before they can reply.
A full duplex transmission mode is a process where data can be sent at the same time in both directions. The full duplex transmission mode is used in telephones, networks and e-mails.
A half duplex transmission mode is a process where data can be sent in both directions, yet the data have to be sent at different times. The half duplex transmission mode is used in hard disks, DVD storage and intercom communications.

Half duplex is mode of communication in which both can send data but only one can receive at a time. Full duplex is mode of communication in which both can send and receive data at a same time.
Half Duplex mode can either send or receive data at one point of time whereas Full Duplex permits simultaneous sending/receiving of data.
A land- line telephone uses transmission in FULL DUPLEX mode in which simultaneous transmission and receiving of information takes place in both direction. There are three modes of transmission: 1.simplex transmission 2.half duplex 3.full duplex

I wouldn't worry about this question until you've learnt English properly. But yes, data retrieval can be considered as half duplex or duplex as it can send a prompt then have data sent to it, or simply create a two way transmission in synchronous.
