Write down the difference between simplex, hall duplex and full duplex transmission mode

Basis for comparison	Simplex	Half duplex	Full duplex
(i) Direction of communication	Communication is unidirectional.	Communication is two directional but, one at a time.	Communication is two directional and done simultaneously.
(ii) Send/Receiver	A sender can send data but, cannot receive.	A sender can send as well as receiver the data but one at a time.	A sender can send as well as receive the data simultaneously.
(iii) Performance	The half duplex and full duplex yields well than the simplex.	The full duplex more yields higher performance than half duplex.	Full duplex has better performance as it doubles the utilization of bandwidth.
(iv) Example	Keyboard and monitor.	Walkie-Talkies.	Telephone.
