What Is The Full Form Of Keyboard

The full form of "keyboard" is "Keyed Input Device."


Who Invented Keyboard

The modern computer keyboard, as we know it today, has evolved over time and doesn't have a single inventor. However, the concept of the keyboard dates back to early typewriters.


One of the earliest practical typewriters was invented by Christopher Sholes, Samuel Soule, and Carlos Glidden in 1868. They developed the QWERTY keyboard layout that is still commonly used today on most English-language keyboards. This layout was designed to prevent the mechanical arms of early typewriters from jamming.


So, while there wasn't a single inventor of the keyboard, Christopher Sholes played a significant role in the development of the QWERTY keyboard layout.
