Types Of Keyboard. There are two major types of computer keyboards: Basic and Extended. The Basic keyboard contains 104 keys and is enough to perform all the functions that can be done on a Windows PC. The Extended keyboard may have additional keys and the design varies among the companies manufacturing them.
This keyboard introduced the 101-key standard US layout that is used today for full sized keyboards. It has also been adapted to the 104-key layout for Windows keyboards with the Windows keys and Menu keys. Since the release of the IBM Model M keyboard there have been many changes to the keyboard we use today.
