what is keyboard?

-
The keyboard is a commonly used input device for computer systems, allowing users to input text and other characters. Most keyboards use the classic QWERTY layout, originally designed for typewriters.

Modern keyboards come in various designs and styles, but all feature the standard QWERTY layout including alphabets, numbers, function keys, and specialized keys like control, shift, alt, and command keys. Additionally, most modern keyboards have multimedia keys for controlling audio and video playback, as well as shortcut keys for frequently used programs.

When a key is pressed on the keyboard, it sends a signal to the computer indicating which key has been pressed. The computer then uses this information to type the corresponding letter, number, or symbol onto the screen. Keyboards can connect to the computer via a wired USB or wireless Bluetooth connection, and are essential for text entry and navigation on any computer system.
