The following outline is provided as an overview of and topical guide to communication:

Communication – purposeful activity of exchanging information and meaning across space and time using various technical or natural means, whichever is available or preferred. Communication requires a sender, a message, a medium and a recipient, although the receiver does not have to be present or aware of the sender's intent to communicate at the time of communication; thus communication can occur across vast distances in time and space.
