What is communication?

Answer:

The term 'Communication' has been derived from the Latin word 'communis' that means 'common'. Thus 'to communicate' means 'to make common' or 'to make known'. This act of making common and known is carried out through exchange of thoughts, ideas or the like. The exchange of thoughts and ideas can be had by gestures, signs, signals, speech or writing. People are said to be in communication when they discuss some matter, or when they talk on telephone, or when they exchange information through letters.
Basically, communication is sharing information, whether in writing or orally.
