Verbal communication includes oral communication methods like interviews and meetings, as well as written communication methods like emails and reports. Non-verbal communication refers to communication through body language, facial expressions, eye contact, and other unspoken means. Barriers to effective communication in business are also discussed, such as physical, attitudinal, psychological, linguistic, and physiological barriers that can disrupt the transmission of information from sender to receiver.
