Formal communication is when one person communicates with another to present information about a subject.
It can also be used to persuade someone to take an action or change their mind.
There are three types of formal communication: written, oral, and nonverbal. Written communication can be found in documents such as memos or emails. Oral communication can be found in presentations or speeches. Nonverbal communications can be found when someone uses gestures to communicate their message with the use of body language or tone of voice.
