Mouse
Definition
In computing, a mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows for fine control of a graphical user interface.
Why It Matters
The mouse revolutionized personal computing by making graphical user interfaces practical and intuitive to use. It is a fundamental input device for most desktop computers.
Contextual Example
A user interacts with their computer by moving the mouse to position the cursor over an icon and then clicking a button on the mouse to "press" it.
Common Misunderstandings
- Modern mice are typically optical or laser mice, which detect movement by tracking a surface with a light sensor.
- Older mice were "mechanical" and used a rubber ball to track movement.
