Answer:
Half duplex
Explanation:
The half duplex is a device which allows the communication from only one side and the other person can only hear at a time. The example is radio. The person speaks from the one side can only speak and on the other the person can only hear. In a full duplex both parties convey their messages to each other. The example includes cellphones, telephones, wireless phones, etc.

They can put checks and balance on each other.
