This document discusses different types of communication. There are two main types - verbal communication, which uses words either spoken or written, and non-verbal communication, which conveys meaning through facial expressions, gestures, body language, etc. Verbal communication can be oral, through speaking, or written. Non-verbal communication includes kinesics (body language), vocalics (paralanguage), proxemics (use of space), haptics (touch), and chronemics (use of time). Communication can also be formal, following official rules along the organizational hierarchy, or informal, occurring spontaneously without conforming to formal processes.
