In personal life, we need to communicate to deal with various concerns and problems of daily life. In professional life also, it is communication that helps us to build healthy relations and credibility with co-workers.

Only speaking/talking is not communication. Communication can take place in many forms. Sometimes, we communicate by ‘talking’ about our ideas, thoughts or emotions; at other times, we may wish to communicate through the written word or even non-verbally. Whatever form we choose, getting the message across is what communication is all about.

Communication is a process that is dynamic, continuous, and irreversible but at the same time, it is reciprocal in nature. It is an ongoing process.
