5.   What is communication cycle?

b.  Idea: The message or idea is the information that the sender wants to convey to the receiver.
c.  Encoding: Encoding refers to the way the sender chooses to compose the message by selecting the appropriate words, symbols or gestures which he/she thinks will be understood by the receiver.
d.  Decoding: The message is then decoded by the receiver. Decoding refers to how the receiver interprets and understands the message.

7.  Why communication is called a two-way process?
