The Worlds Largest Operational Telephone

A telephone, also called phone is a communication tool. Originally it was an electric tool transmitting analogue speech along wires. Now it is an electronic tool sending digital signals on wires or radio transmission. Using a telephone, two people who are in different places can talk to each other. Early telephones needed to be connected with wires which are called fixed or landline telephones. Now telephone calls can be sent with radio. This is called wireless or cordless.


Alexander Graham Bell was the first person to patent the telephone, in 1876. Early telephones were wired directly to each other and could only talk to the phone that they were connected to. Later, telephone exchanges allowed connecting to other telephones. During the 20th century the machines that made the connections were automated.
