Answer:
Function keys, typically labeled F1 through F12, are keys on a computer keyboard that have predefined functions within software applications or operating systems, such as opening help menus, saving files, or refreshing a page. Special PC keys, on the other hand, refer to keys that serve specific purposes outside of typical alphanumeric input, such as the Windows key, Alt key, Ctrl key, or the key with the company logo on it. These keys often have specific functions in conjunction with other keys to perform tasks like shortcuts, system commands, or accessing special features.
