An intercom is a device that makes it possible for people to communicate between different rooms or areas of a building. Airplanes use intercoms so the pilot can tell passengers, "Fasten your seat belts!"
Many schools have an intercom system, so that students, teachers, and administrators can broadcast announcements to every classroom. Some intercoms operate as one-way communication, while others are two-way intercoms: a friend's apartment building might have an intercom you can speak into, telling her you've arrived, and she can respond, telling you she's buzzing you in. Intercom, dating from 1940, is a shortened form of intercommunication.
