The first computer mouse was made of wood and had two metal wheels that could move in two directions. It was connected to the computer by a cable and was used to move the cursor on the screen.
The computer mouse was a revolutionary invention that changed the way people interacted with computers. It made it possible to use a computer without having to type in commands, and it made it easier to navigate through documents and files.
The computer mouse has evolved significantly since it was first invented. It is now smaller, more accurate, and more affordable. It is also available in a variety of different shapes and sizes, and can be used with a variety of different computers and operating systems.
