A computer keyboard is a peripheral input device that allows users to input text, commands, and other instructions into a computer. Computer keyboards come in different styles, including standard, ergonomic, and gaming keyboards. Standard keyboards are the most common type and feature a layout that includes alphanumeric keys, function keys, and navigation keys. Ergonomic keyboards are designed to reduce strain and discomfort associated with long hours of typing, and they feature a curved or split design that promotes a more natural wrist and hand position. Gaming keyboards are optimized for gaming and feature additional keys for gaming-specific functions and customizable backlighting. Most computer keyboards use a wired USB connection, but wireless Bluetooth keyboards are also available. Some computer keyboards may also feature programmable keys or customizable software, allowing users to create shortcuts and automate tasks for increased productivity.
