A normal keyboard is a standard, widely-used computer input device that features an arrangement of letters, numbers and symbols on raised keys that can be easily pressed with the fingers. It typically has 104 or more keys, including alphabetic, numeric, and special function keys, as well as navigation buttons such as arrow keys for moving a cursor or selecting text. The term "normal" in this context refers to the standard layout of the keyboard, which is commonly used for typing on a computer or other electronic device.
