On this Earth every creature has its own language and method for communicating with each other. Without Communication nobody can live properly in the society. Communication is a process of exchanging information, ideas, thoughts, feelings and emotions through speech, signals, writing, or behaviour. In communication process, a sender(encoder) encodes a message and then using a medium/channel sends it to the receiver (decoder) who decodes the message and after processing information, sends back appropriate feedback/reply using a medium/channel.
