communication is two-way. An interactive conversation between two people or more in the daily life of man. Must have a chat to talk to the media, the other party understand what they say, like a conversation between vendors and customers need to inquire about the price of goods sold.

all the above. All communication is all about Including one-way communication. And two-way communication Communication is effective It depends on the ability of senders and receivers. That interpretation was correct or not.
