I need a help on my stupid assignment, here are the questions...
What is the difference of Keyboard and joystick?
What is the difference of Mouse and Trackball/Track Ball?
Any possible answers?
What exactly do they want from the first question? The answer is so obvious. They're entirely different things.
But a Track ball, I can't even understand. Try looking that one up.
A keyboard is used for typing things out while a joystick works similarly to a trackball, but it tilts, not rolls.
A mouse, you have to move the entire thing by hand, while you only have to roll the trackball.
