Good answer !!!
(Generally) communication IS a two way process.
Even if the information or data is coming from one way; the receiver must acknowledge the receipt of information - which is indicated by the FEEDBACK loop in the diagrams.
Technically, communication can be a one-way process, like top to bottom in organizations (chairman's address, circular, notices), broadcast media (TV, radio); or say, a protest (down to top) etc. However there is always a provision for feedback, making it a two-way process.
In Communication technology, mobile phone etc. offer TWO-WAY communication, simultaneously; and are called FULL-DUPLEX system; whereas Walkie Talkie Wireless System offers HALF-DUPLEX communication, which is again a two-way communication, but at one time only one party can speak/listen.
Example of true one way communication is when astronomers send messages/signals to distant stars in distant galaxies. Another example could be your communication with God, :-D , but i don't think many would agree that it a one-way communication. :icon1:
