A keyboard is a computer input device that uses an arrangement of buttons or keys to act as mechanical levers or electronic switches.The main input method for computers was via teleprinter-style keyboards following the decline of punch cards and paper tape.
Keys on keyboards typically have symbols engraved or printed on them, and each press of a key typically corresponds to a single word. To produce some symbols, you need to press and hold several keys at the same time or in sequence.
