A keyboard is a peripheral input device used to input text, characters, and commands into a computer or other electronic device. It typically consists of a set of keys, including letters, numbers, symbols, and function keys, arranged in a specific layout, such as the QWERTY layout commonly used in English-speaking countries.
Keyboards come in various forms, including the traditional wired keyboards connected via USB or PS/2 ports, wireless keyboards that use Bluetooth or RF (radio frequency) connections, and virtual keyboards found on touchscreen devices like smartphones and tablets.
Keyboards are essential for interacting with computers and are used for typing documents, sending emails, browsing the internet, playing games, and executing commands in software applications. They often feature additional keys for specific functions like adjusting volume, controlling media playback, and launching applications, as well as specialized keyboards tailored for specific tasks such as gaming or audio/video editing.
