Meaning – The term mouse, refers to the commonly used pointing device that contains one or more buttons with which a user can interact with a computer system. For example, using a mouse button, a user can select objects or choices, initiate actions, or directly manipulate objects.
All mice have at least one button, though most mice have two or three. Some also have additional buttons on the sides, which can be assigned to different commands. Most mice also have a scroll wheel, which lets you scroll up and down documents and Web pages by just rolling the wheel with your index finger.
Example of usage – “Early mice tracked movement using a ball in the bottom of the mouse. This “mouse ball” pushed against different rollers as it moved, measuring the mouse’s speed and direction. Optical mice are more accurate than roller-based mice and they have the added bonus of not getting dirty inside.”
