• Capacitor — Help to store electronic information in electric field.

• Diode — For flowing the current in one direction.

• Transistor — For amplify or switch electronic signals.

• IC — This is small wafer, and made of silicon

Now these days, almost everybody aware about Mouse, but anyone in the mind some questions can be arise such as what are the uses of a computer mouse? Then here we will explain about awesome five to ten uses of computer mouse.

Movement Mouse Cursor: This is main function of mouse is moving form, when we roll mouse up or down then mouse cursor move on the computer screen.

Selection: With using mouse users can select any images, text, any file, and folder etc. And, then can perform other tasks such as copy, delete and paste.

Drag: Mouse allows to users for moving any objects with the help of drag — drop function. In this method, firstly select object then can be move object while pressing the mouse button, and drop object where to place it.

Hovering: When mouse cursor over on the clickable object then display the information without pressing any button of mouse, and change the color of links as well. Can be go destination page, after pressing that hyperlink.

Scroll Up & Down: If, you perform any activates on the enlarge document, then you need mouse’s scroll button for doing up and down your document page, otherwise user can up & down scroll bar while pressing mouse cursor.

Program Execution: With the help of mouse, users can execute many task such as open file, close folder, maximize-minimize any windows, double clicks for opening object and more.

Editing: Mouse allows to users to editing images in the image editor software such as Photoshop, CorelDraw, and Picasa etc.

Playing Game: With using mouse, users can play various games such as chase game, in that game need mouse for selecting any particular objects.

Combination Activities: Many task can perform by using some keyboard’ keys along with mouse such as CTRL+Mouse click for hyperlink in new windows and CTRL+Scrolling for zooming in — out screen etc.

Operate Audio/Video: Some special mouse have multimedia buttons for controlling the audio/video such as do enhance/ down volume level etc.

Here, we will discuss about core working principle of mechanical and optical mouse. Such as

Here, we will spread light on some mechanical mouse working principles are:

• Mouse has to contain the rubber ball that is touch with desktop and rolls while moving the mouse.

• Two rollers are existed in the mouse, this touch with ball. One roller placed that detect the motion in X directions; other suited 90 degrees that identify the Y direction’s motion. When roller touch ball then that is able to detect both X and Y motion.

• Every roller linked with a shaft, and shaft allows spinning disk on its hole. Both shaft and disk spin while rolling the roller.

• Infrared LED and an infrared sensor installed on the mouse’s circuit board. LED spreads the beam of light, and disk breaks them. In entire process infrared sensors identify all pulses that are coming from disk after splitting. The pulse’ rate depend on the speed of mouse and it traveling distance.

• Processor access all pulses that are coming from infrared sensors and convert them into binary form such as 0 an 1 because computer only can understand binary language , and finally send to computer with the help of mouse ‘cord.

Optical Mouse Working Principle — Optical mouse is totally different to mechanical ball mouse. This is because; in optical mouse, all operations get perform by LED (light emitting diode) and photo detector. Both get place near each other.

Work of photo detector is gather all beam of light and bounced off on the surface area. In photo detector, lens embedded those collect all beams and forward to CMOS (Complementary Metal Oxide Semiconductor) sensor. Photo detector is a high speed camera and able to transfer 1500+ images in per second towards to CMOS sensor with the help of their lens.

The CMOS sensor captures images of the surface with the help of a Digital Signal Processor (DSP), which is also known as the Optical Navigation Engine. This technology is used in modern optical mice to track movement accurately. The Optical Navigation Engine works as the brain of the mouse because it is able to compare and compute many pictures among different images. These images contain information about motion and are sent to the computer. Finally, the computer controls the movement of the pointer on the screen based on these coordinates.

Now, finally you have understood that optical mouse how to work smoothly.

• Mostly use with desktop computer systems.

• When buy new brand computer then get mouse with computer..

• No need more training for using it.

• Solve many problems when use mouse while keyboard's keys.

• Freedom for movement flexibility.

• Freedom for selection of mouse according user’s comfortable because mouse have huge varieties are available in the market.

• Portability- Easy to carry one place to other place.

• Most preferred device for graphic applications areas.

• Some multi function mouse provide to users more flexibility for cursor movement.

• Having faster to traditional mouse.

• No need more space for using it.

• Low cost.

• Easy to operate indoor and outdoor areas

• Need flat surface.

• Need services regular basis.

• More dust sensitive.

• Some time, dragging operations is difficult by user.

• Mouse can damag easily.

• May be, can be eye sight problems due to more use of mouse rotation.

• Need little space for using.

• Palm can be getting pain due to use mouse long time.

• Not easy task for giving text input to computer.

• Getting very low performance due to virus infection.
