what is keyboard

A keyboard is a peripheral input device that allows users to input text, characters, and other commands into a computer or any other electronic machinery. It is modeled after the typewriter keyboard and consists of an arrangement of buttons or keys that act as mechanical levers or electronic switches. Keyboard keys typically have a set of characters engraved or printed on them, and each press of a key typically corresponds to a single written symbol. However, producing some symbols may require pressing and holding several keys simultaneously or in sequence. In addition to letters, numbers, and symbols, keyboards also have other keys that can prompt the computer to execute system commands. The design of the keyboard comes from the typewriter keyboards, and numbers and letters are arranged on the keyboard in a way that helps to type quickly. The most common keyboard layout is the QWERTY design, which is derived from the typewriter keyboard. The keyboard also includes many other keys, such as Alt/Option, Control, and Windows key, which can be used as shortcuts to perform a particular operation by combination with other keys.
