Mouse

=About the Mouse=

__Intro__
==Mice first broke onto the public stage with the introduction of the Apple Macintosh in 1984, and since then they have helped to completely redefine the way we use computers. Every day of your computing life, you reach out for your mouse whenever you want to move your cursor or activate something. Your mouse senses your motion and your clicks and sends them to the computer so it can respond appropriately.==

__What is a mouse?__
==-It is a hardware device that allows the user to control the cursor to manipulate data without complicated commands. **Basically, a mouse is just a pointing** **device interacting with the PC. You** **can select, drag, draw, move** **pictures, files, and navigate all over** **the applications of your computer.**==

- There are more buttons on the side
-Most of the mouses are now wireless

=**Inside a Mouse**= -A ball inside the mouse touches the desktop and rolls when the mouse moves. n -Two rollers inside the mouse touch the ball. One of the rollers is oriented so that it detects motion in the X direction, and the other is oriented 90 degrees to the first roller so it detects motion in the Y direction. When the ball rotates, one or both of these rollers rotate as well. -The rollers each connect to a shaft, and the shaft spins a disk with holes in it. When a roller rolls, its shaft and disk spin. -On either side of the disk there is an infrared LED and an infrared sensor. The holes in the disk break the beam of light coming from the

-LED so that the infrared sensor sees pulses of light. The rate of the pulsing is directly related to the speed of the mouse and the distance it travels. -An on-board processor chip reads the pulses from the infrared sensors and turns them into binary data that the computer can understand. The chip sends the binary data to the computer through the mouse's cord.


 * Tilting Scroll Wheel** nA recent innovation in mouse scrolling is a tilting scroll wheel that allows you to scroll onscreen both horizontally (left/right) and vertically (up/down). The ability to scroll both ways is handy when you are viewing wide documents like a Web page or spreadsheet.


 * Types Of Mice**


 * Wireless Mice** •Wireless mice make use of infrared signals to connect to your computer. •However, the mouse’s emitter and the infrared receiver must always be within the other’s line of sight
 * Apple Mice** •Apple and Macintosh computers make use of a different kind of mouse, one that only uses a single key, unlike the other types of mouse, which make use of two keys.
 * Ball Mice** •The Ball Mice is the most common type of mouse today. • It features a rubber ball placed at the bottom of the mouse, which, when the mouse is moved, in turn moves two small wheels placed inside the mouse. •The wheels allow the mouse to respond to speed and direction.
 * Optical Mice** •The optical mouse does not make use of a ball at its bottom. •It has a low-power laser light underneath it, which detects changes in texture. The changes are then converted inside the mouse and sent to the computer, which processes the directional and speed movement of the cursor. It is an asset in graphics applications, and it makes computer operation easier in general. It does not need cleaning, because it has no moving parts. This all-electronic feature also eliminates mechanical fatigue and failure.

¡ Works more efficiently and easy to repair ¡ Has a better and sensor that responses quickly and smoothly ¡ Can be used on many different surfaces ¡ Very simple to use ¡ Very inexpensive and easy to find
