A ringtone is a sound or noise that alerts the user to an incoming call, text message, or notification. Originally made by electromechanically striking bells, the term is now commonly used to refer to customizable sounds on mobile phones.
A telephone is a telecommunications device that allows users to communicate with each other over long distances. It converts the sound of a human voice into electronic signals that can be transmitted over telephone networks and played back in audio form to the user.
The word "telephone" derives from the Latin term Telemeter, which means "a device for transmitting messages from one person to another". Today, a telephone can be any portable electronic device capable of making and receiving calls.
