Communication is a process whereby information is enclosed in a package and is channelled and imparted by a sender to a receiver via some medium.

Communication requires that all parties have an area of communicative commonality. There are verbal means using language and there are nonverbal means, such as body language, sign language, paralanguage, haptic communication, chromatics, and eye contact, through media, i.e., pictures, graphics and sound, and writing.

The person who initiates the communication process is normally referred to as the sender.
