Difference between Simplex, Half duplex and Full Duplex Transmission Modes
In electronics, data transfer between sender and receiver follows a particular mode which is also known as Transmission mode. On the basis of nature of data sent and data received we can distinguish between Transmission mode as Simplex, Half-duplex and Full-duplex.
Following are the important differences between Simplex, Half duplex and Full Duplex Transmission Modes.
| Sr. No. | Key | Simplex Mode | Half duplex Mode | Full Duplex Mode |
|---|
| 1 | Definition | Simplex Mode of transmission is the mode of transmission in which there is only unidirectional flow of data i.e., participant does only one task which means sender can only send the data and can't receive. | Half duplex Mode is the mode of transmission in which there is bi-directional flow of data but one at a time, i.e., Sender can send as well as receive the data but does one task at a time. | Full Duplex is the mode of transmission in which again there is bi-directional flow of data i.e., Sender can send as well as receive the data at the same time. |
| 2 | Data flow | As mentioned in above point, data flow in case of Simplex Mode is UniDirectional. | On other hand in case of Half duplex data flow is two-directional but one at a time. | In case of Full Duplex data flow is two directional and is simultaneous. |
| 3 | Performance | Simplex Mode of transmission is treated as worst performing mode of transmission as it takes longest time in data transmission. | On other hand performance of Half-duplex is better as compared to Simplex but is lower as compared to Full-Duplex mode of transmission. | Full-Duplex has best performance as compared to that of Simplex and Half-Duplex mode of transmission. |
| 4 | Example | Example of Simplex mode of transmission are Keyboard and monitor. | However example of Half-Duplex mode of transmission is Walkie-Talkies. | On other hand example of Full-Duplex mode of transmission is Telephone. |
