                Recap


           • Communication is defined as a process of exchange of information between two or more people by speaking, writing,
           signalling, or using any other effective medium.
           • The main elements in the communication cycle are sender, message, encoding, communication channel, receiver, decoding,
           response/feedback.
           • Different methods of communication are Verbal, Non-Verbal and Visual Communication.
           • Verbal Communication is the most popular form of communication where the transmission of messages occurs with the
           usage of words that can be in oral or in written form.
           • Non-Verbal Communication is defined as communication through physical and physiological cues without using spoken
           or written words.
           • Visual Communication is the transmission and interpretation of information by using visual resources like photographs,
           videos, art, drawings, sketches, charts and graphs.
           • Body language is a very important part of non-verbal communication that reveals your true thoughts and emotions.
           • Feedback is a response of the receiver with respect to the message received from the sender.
           • A communication cycle is incomplete and irrelevant without feedback. It works as an indicator to ensure a successful
           transmission of the message.
           • Formal Feedback follows a predefined format or blueprint to construct the structure of the feedback.
           • Descriptive Feedback is a detailed analysis in written or oral communication that helps the learner understand strong and
           weak points.
           • Non-Descriptive Feedback is written or oral communication that provides meaningful information but does not contain
           detailed analysis and description of the feedback.
           • Specific Feedback focuses on the specific points of utmost importance and should be conveyed to the sender.
