Verbal communication includes both oral and written communication. Oral communication involves speaking to convey messages, such as conversations, presentations, and speeches. It allows for immediate feedback but lacks records and can lead to misunderstandings. Written communication involves using the written word to share messages through letters, emails, manuals, and other documents. It provides accuracy, permanent records, and legal evidence but is more time-consuming and impersonal than oral communication. Both oral and written communication are essential forms of verbal communication.
