Communication involves sending and receiving information through various channels between people. Effective communication skills are important for both careers and personal relationships. There are verbal, nonverbal, and paraverbal forms of communication, and barriers can occur due to semantics, emotions, organizations, or individuals. Developing good communication involves skills like clarity, integrity, timing, adequacy, exploring related skills, maintaining eye contact, body awareness, conveying thoughts, and practicing communication through various means like speaking, writing, and visuals.
