Communication: a two-way process

Communication is a two-way process in which individuals are able to understand each other.

From what I learned from my previous course, Communication has 5 elements.

The sender, the message, the receiver, the feedback and the channel of communication. Without these elements, communication has no use at all.

But most importantly, communication cannot be effective without a feedback. That's why it's called a two-way process because after the sender sends the message, the receiver should be able to interpret it by means of feedback. :)
