Of course a piano has a keyboard. A piano is an instrument where pressure on a key causes a hammer to strike a string, making it vibrate and create a tome. An electronic keyboard uses the key as a switch to make an electrical circuit generate the tone. Plus the electronic keyboard is a lot easier to carry.
A piano is an instrument in itself and it produces sound when the small wooden sticks tap the reeds inside. While a keyboard is more of an electric device that produces artificial sounds when played. You need a supply of electricity or a battery to convert the electric energy into sound energy.
