The various types of commonly used transmissions are as follows:

- Simplex Transmission: This type of data transmission involves data to be moved only in one direction. In this no data can be sent back using the same channel. A

good example of this form of transmission can be found in a keyboard.

- Half Duplex Transmission: This type of transmission allows data to be transferred in both directions but not at the same time. One end transmits while the other

receives.

- Full Duplex Transmission: In this type of transmission data can be sent and received at the same time. There are no two different modes such as transmit and

receive.
