Based on the direction of data from sender to receiver, there can be 3 types of transmission modes which are as follows
Simplex:In simplex mode, among the two devices which are communicating with each other, one device can only be a sender and the other can only be a receiver. Thus the sender device will not receive data but will transmit data, and the receiver device will only receive data but will not transmit or send any data. This transmission is unidirectional. Examples: Keyboards and monitors or displays, traditional FM radios etc. Traditional FM radios only output broadcasted or transmitted audio from stations, but does not communicate back. Advantage
Disadvantage
Half-DuplexIn half-duplex, both devices which are communicating with each other can send and receive data, but not at the same time, that is, when one device is sending data then another device can only receive that data but can’t send data back. This is like a narrow bridge where vehicles from both end of the bridge can cross the bridge but not at the same time. Examples: walkie-talkie, CB radios etc. Advantage
Disadvantage
Full-DuplexIn full-duplex or duplex mode, both devices can send and receive data at the same time. Here is this transmission mode, data going in a direction will share the capacity of the transmission medium with the data going in another direction. This sharing can be obtained by two ways, such as, by sharing the capacity of the medium, or having two physically separated transmission paths. Examples: telephone, cellphone networks etc. Advantages

Next TopicModels ← prev next → Which mode of communication can send and receive data simultaneously?Full duplex mode: In full-duplex mode, Sender can send the data and also can receive the data simultaneously. It is two-way directional communication simultaneously.
Which transmission type allows both parties can transmit and receive information simultaneously?Sometimes called full duplex, to differentiate from half-duplex. With a duplex radio, two frequencies used—transmit and receive. The radio is able to transmit and receive simultaneously, allowing both parties to speak and listen at the same time like a telephone conversation.
In which communication mode each station can both transmit and receive but not at the same time?Half-duplex data transmission allows data to flow in both directions but only in one direction at a time. Semi-Duplex is another name for it. In other words, each station can transmit and receive data at the same time, but not simultaneously.
