Keyboards are essential input devices used to communicate with computers and other electronic equipment. They typically feature a layout of keys, each assigned a specific function, allowing users to type text, enter commands, and navigate software applications. Keyboards come in various forms and designs, including wired and wireless models, ergonomic designs for comfortable typing, and compact options for travel or limited workspace. Desktop computers often include keyboards as part of a bundled package, but separate keyboards can also be purchased for use with laptops, tablets, and other devices. While printers do not directly relate to keyboards, they are commonly used in conjunction with desktop computers and may require keyboard input for setup or operation.
