Communication has evolved over time from gestures to speech to writing. The purpose of communication is to educate, entertain, persuade, socialize, maintain relationships, and exchange information. There are various types of communication including verbal communication like oral and written communication, and non-verbal communication such as gestures, eye contact, and body language. Barriers to effective communication can be physical, language, cultural, perceptual, emotional, or interpersonal. Developing essential skills like listening, speaking, reading and writing as well as overcoming barriers can help improve communication.
