The telephone is a communication contraption which transmits sound between any two telephones, often for the purpose of allowing people to talk back and forth between one another. Throughout its history, many improvements and updates have been bestowed upon the device. The telephone has become one of the most popular household devices in America, and throughout the entire world.
Alexander Graham Bell is accredited as the first inventor of the telephone, however this is a widely disputed debate. All telephones maintain a microphone and an earphone -which are usually constructed as a handheld device which is held up to the mouth and ear -as well as a ringer of some sort in order to hear when a call is incoming, and a keypad (or in older cases, a dial) to call other telephones.
The telephone was developed in the 1870's and since then has been rapidly evolving into the "smart"phones of today. Telephones started out as a land-line device, which needed an operator; to a slightly more developed version of land-line phones; eventually changing into cellular phones, which required no operator, or external wires, and allowed for heavily increased mobility. Cellular phones developed in a different fashion than land-lines, becoming smaller and smaller, and they can now be used almost all over the world!
