Write about data communication mode with its types.

Data communication mode refers to the mechanism of transferring of data between two devices connected over a network. It defines the direction of the flow of information between two communication devices.

The types of data communication mode are:

1. Simplex

In this mode, data travels only in one direction (from A to B). For clarification, you can look at radio broadcasting, television broadcasting, etc. where data travels only in one direction. Other examples of Simplex are computer to printer communication and keyboard to computer connection, etc.

2. Half duplex

In this mode, data can travel in both direction but not at the Same time (i.e. one by one). Data travels only in one direction at a time. For eg. From A to B at first, then from B to A. Walkie Talkie is its perfect example.

3. Full-duplex

In this mode, data can travel in both directions at the same time. The present world is highly familiar with this mode and this is considered best among all three modes. Telephone and mobile phone communication is its best example.
