Question

Different between formal and informal communication

Answer 1

in formal communication we have to provide salutation while in informal communication we need not to do so.

Answer 2

1. You use formal communication when you're talking to somebody elder than you or of a higher rank/post than you. Formal communication includes terms like 'Sir', 'Madam', etc etc.

2. Informal communication is used when you're talking to your friend, classmate, etc. You may use slang when speaking informally.
