Communication is used to disseminate information by allowing people to share information with each other in a variety of ways. This can be done through verbal communication, such as talking face-to-face or over the phone, or nonverbal communication, such as through written documents, emails, website postings, or even through social media. Communication can also be used to spread information through the use of broadcast media, such as television, radio, or newspapers. In any case, it is important to ensure that the communication is clear, effective, and targeted to the right audience.
