A **communication system** is a system in which communication takes place.

For example, the number system, braille, calendars, `Backus-Naur Form`_, `chess notation`_, `Hungarian notation`_, `Polish notation`_, `Big O notation`_, regular expressions, Chinese writing systems, hieroglyphics_, and the `International Phonetic Alphabet`_.

This includes animal communication systems and human communication systems, such as language.

A communication system essentially consists of five parts: an information source, a transmitter, a channel, a receiver, and a destination. [1]
