In data communication, there are three types of communication styles; they are Simplex, Half-Duplex and Full-Duplex. Here we discuss about their characteristics with examples.
Simplex:
In this communication style data can send only and basically it is one way or uni-direction communication. This type of communication is not widely used for transmit trusted data because it can not send any error or control signal to sender terminal.
This style of communication is vastly used in Radio and TV where we can see and hear or receive data only but we can not send any information data by the same channel.
Half-Duplex:
Half-Duplex is another type of communication style where data can and send and receive but not at the same time. In this communication type, if data is send from one end, then we can not send data from another that means communication establish in one direction.
This communication vastly used in walkie-talkie, intercom, string phone etc. The practical example is, when we talk with walkie-talkie or intercom we can talk only one way that means one can speak at a time and another should hear on that time and after hearing he has to say over to start speaking from other end.
Full-Duplex:
In Full-Duplex communication, data can send and receive at the same time from both ends that means both way bi-direction communications simultaneously. In this style we can send data from A end to B end and B end can send data to A end at the same time without any interruption or overlapping data.
A Full-duplex Ethernet with two twisted pair is the best example of Full-Duplex communication which is widely used for faster data communication and it also increases data capacity. We can use this for multipurpose data communication at the same time like internet, cable TV and phone etc with the same cable.
