What are transmission modes
The basic work of the transmission mode is that to define the direction of the signal flow between the linked devices. Through the transmission modes, you can judge the device work and utilize it according to its transmission mode. However, there are three modes of transmission: Simplex, Half Duplex and full Duplex.
Simplex mode is as simple as it name. In the simplex mode, you can only receive the data from the other side. For example, the CPU sends the data to the monitor for displaying it on screen however, the CPU is sending the data and monitor is receiving that mean the motherboard is doing the simplex mode transmission because the monitor is not sending any data to CPU only receiving. A keyboard is also a good example of simplex mode.
Half – Duplex Mode
In the half-duplex mode, you can only send or receive the data at a time. You cannot send or receive the data at a time. When device A is sending the Data at the time device B can only receive the data. Let us take a good example of it for clearing the concept of the half-duplex mode. If there is a one way road and both the end cars wants to travel at that time when the right side people run the cars on the one way road then the left side people have to wait. You can also take the example of walkie talkies whereby only one person can speak at a time while the other person only listens.
Full – Duplex Mode
In the full–duplex mode, both the devices can communicate each other at a time. Computer A can send or receive the data from Computer B and Computer B can send or receive data from Computer A. Both the stations can transmit and receive simultaneously. The sharing of the data can take place in two ways. The telephone is a good example for understanding the concept of the Full Duplex because while talking on the telephone both the person can listen or speak at a time.
