While most people don't want to see a mouse running around in their home, they typically don't have a problem seeing one sitting by their computer. This is because, along with the keyboard, the mouse is one of the primary input devices used with today's computers. The name comes from the small shape of the mouse, which you can move quickly back and forth on the mouse pad, and the cord, which represents the mouse's tail. Of course, if you are using a wireless mouse, the analogy does not work so well.
If you have more than one mouse, they are called mice, not "mouses," as some people tend to say. All mice have at least one button, though most mice have two or three. Multi-button mice also usually have a scroll-wheel, which lets you scroll up and down documents by just rolling the wheel with your index finger. The movement of older mice was tracked by a ball in the bottom of each mouse. This "mouse ball" pushed against different rollers, which measured the mouse's speed and direction. However, now most mice use optical technology, which uses a beam of light to track the mouse's motion. Optical mice are more accurate than roller-based mice and they don't have the problem of getting dirty inside. |
