Two-way communication allows for instant feedback, seeking for clarification and interaction between the sender and the receiver. It is typically seen as more efficient than one-way communication for information and feedback delivery.
Communication refers to the process of passing a piece of information (or message) from one end (sender) to a destination (receiver). In some cases, communication may take a linear path and is unidirectional. This model is called one-way communication. Another model of communication involves an interaction between the sender and receiver. This is called two-way communication. One demerit of one-way communication is the lack of interaction. There is also a possibility of never finding out the fate of a message, as there is no feedback.
On the other hand, the two-way communication model is often more efficient than one-way communication because it allows both the sender and receiver to interact instantly. This interaction, which involves feedback and normal dialogue, helps in eliminating vagueness and ensures clarity of information.
Presently, a lot of communication takes place via the Internet. Web technologies have made it very easy for people to communicate effectively. Computers provide a visual interface that allows people to send messages on different platforms. Social networking has gone viral, as opposed to email messaging, because the former relies on instant messaging technology whereby people can communicate quickly and effectively.
Verbal communication involving one-on-one engagement is also another good example of two-way communication. It is seen as the most efficient way of personal interaction whereby emotions are expressed and understood well.
