• A computer keyboard is an input device that uses buttons or keys to insert characters and functions into a computer system. It is the most common method of text entry. Individual letters, numbers, and special characters, as well as keys for specialised operations, are often found on a keyboard. A wireless or cable connection is used to connect a keyboard to a computer system.
• A person can type a document, use keystroke shortcuts, access menus, play games, and do a variety of other things with a keyboard. Depending on the manufacturer, the operating system they're designed for, and whether they're coupled to a desktop computer or part of a laptop, keyboards can have different keys. However, these keys, also known as keycaps, are generally the same size and form from keyboard to keyboard.
