Communication is an act of exchanging ideas, information, and emotions from one person to another or one place to another place. Communication can be classified into two- Verbal and Non-verbal communication. The word verbal means words. Non-verbal communication means communication without using words. In other words, non-verbal communication is an act of exchanging ideas, information, and emotions from one person to another by using symbols, visuals, dress code, postures, silence, eye contact, space distancing, and body language.
Albert Mehrabian, a professor of psychology, estimates that 55% of the impact of a message is through the non-verbal mode. Non-verbal communication may be visual or auditory. One of the most important advantages of non-verbal communication is that language barriers can be removed by using the non-verbal signs and symbols. Apart from this it also helps us to make instant communication possible. For example, traffic signals. Visual tools help a presenter to present very systematically and very quickly and it helps the readers and audience to understand complicated large quantity of data.
