Communication is the process of sending and receiving information between people. The most common forms of communication are speaking, body language, and writing. Spoken language is informal and spontaneous, allowing for real-time feedback. Written language is more formal and organized, but there is a time lag between production and reception and no visual or audio cues. Effective communication depends on factors from both the speaker and listener like their attitudes, purposes, credibility, and the message being conveyed through the chosen channel.
