The keyboard is the most commonly used and important input device. Through the keyboard, English letters, numbers, punctuation marks, etc. can be input into the computer to issue commands, enter data, etc. to the computer. There are also keyboards with various shortcut keys. As time goes by, independent products with various shortcut functions gradually appear on the market and are sold separately, with dedicated drivers and setting software, and personalized operations can also be realized on compatible machines.

In order to meet the needs of different users, the conventional keyboard has three indicator lights: CapsLock (letter case lock), NumLock (numeric keypad lock), and ScrollLock (scroll lock key) (some wireless keyboards have omitted these three indicator lights) to indicate the current status of the keyboard. These indicator lights are generally located in the upper right corner of the keyboard, but some keyboards use indicator lights built into the keycaps. This design makes it easier to judge the current status of the keyboard, but the process is relatively complex, so most ordinary keyboards do not use this design.

Panel area, Num numeric auxiliary keyboard area, F key function keyboard area, control key area, and a shortcut key area is added to the multi-function keyboard.

The keyboard circuit board is the control core of the entire keyboard. It is located inside the keyboard and is mainly responsible for key scanning identification, encoding and transmission interface work.
