A computer keyboard is one of the most common input devices for a computer. A Computer Keyboards, like an electric typewriter, is made up of buttons that are used to create letters, numbers, and symbols, as well as perform other functions. The sections that follow provide more detailed information and answers to some of the most frequently asked questions about the keyboard.

Keyboard keys (buttons) are typically engraved or printed with a set of characters, and each key press corresponds to a single written symbol. Some symbols, however, may necessitate the simultaneous or sequential pressing and holding of several keys. While most keys generate characters (letters, numbers, or symbols), others (such as the escape key) can instruct the computer to run system commands. In a modern computer, the software interprets key presses: the information sent to the computer, the scan code, tells it only which physical key (or keys) was pressed or released.

Increasing global promotion of healthy typing techniques is expected to restrain global Computer Keyboards Market growth during the forecast period.

For most of the twentieth century, the teleprinter's keyboard played an important role in point-to-point and point-to-multipoint communication, while the keypunch device's keyboard played an equally important role in data entry and storage. The first computers used electric typewriter keyboards: the ENIAC computer used a keypunch device as both the input and paper-based output device, while the BINAC computer used an electromechanically controlled typewriter for both data entry onto magnetic tape (rather than paper) and data output.

While typewriters are the most direct ancestor of all key-based text entry devices, the Computer Keyboards as a device for electromechanical data entry and communication is largely derived from the utility of two devices: teleprinters (or teletypes) and keypunches. The layouts of modern computer keyboards were inherited from such devices.
