A telephone is a device used for transmitting sound over long distances by converting sound waves into electrical signals and then back into sound waves. It allows people to communicate with each other by speaking into a microphone and listening through a speaker or earpiece. Traditional telephones are connected by wires, while modern telephones can also be wireless and use cellular networks or the internet to make calls.
