Telephone, Twisted Pair and Graphophone

A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are not in the same vicinity of each other to be heard directly. Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of canceling out electromagnetic interference from external sources. A graphophone was the name and trademark of an improved version of the phonograph. It was invented at the Volta Laboratory established by Alexander Graham Bell in Washington, D.C., United States.
