                                         what is a computer mouse

A mouse is an input device, originally named Pointing Device. It is mainly used in selecting, moving and opening and closing items on a computer screen. Through the mouse, the user instructs the computer.

                           who was invented

Computer mouse was invented by World War II soldier Douglas C. Engelbart in 1968.

A simple computer mouse usually looks like a real mouse. It is small and rectangular, connected to the computer via a cable. It is something like this.

                           introduction of buttons 

A simple Mouse usually has three buttons, which can be seen in the cheetah above.

The first and second buttons are known as Primary Button and Second Button (Right Button) respectively.

They are called Right Click and Left Click in common language. And the third button is also called Scroll Wheel or Chakri. Now more than three buttons have started coming in the modern Mouse, which have different functions.

                        

                      TYPES OF MOUSE

• Mechanical Mouse
• Optical Mouse
• Wireless Mouse
• Trackball Mouse
• Stylus Mouse

   1. Mechanical Mouse

This mouse was invented by Bill English in 1972. The Mechanical Mouse used a ball for instructions. Hence it is also called Ball Mouse.

This ball could be rotated from right to left and up and down.

2. Optical Mouse

This mouse works on LED - Light Emitting Diode and DSP - Digital Signal Processing technology. There are no balls in the optical mouse. A small bulb is installed in its place.

So when the mouse is moved, the pointer moves. And through the buttons in it, we instruct the computer. Nowadays this type of mouse is used.

They are connected to the computer by a wire. Which also supplies electricity to it. Optical Mouse is easy to use.

3. Wireless Mouse

Wireless mouse is called Wireless Mouse. It is also called Cordless Mouse. This mouse is based on Radiofrequency (RF) technology. But its texture is like optical mouse.

So a Transmitter and Receiver is needed to use it. The transmitter is made in the mouse itself. And Receiver is made separately. Which is installed in the computer.

This mouse requires battery to operate. So we have to buy a small battery separately.

4. Trackball Mouse

The design of this mouse is also similar to that of some optical mouse. But it uses a trackball for control.

To instruct the computer, the user has to spin the ball with his fingers or fingers. This mouse does not give us much control. And it also takes time to run.

5. Stylus Mouse

This type of mouse is also called gStick Mouse. Because Gordon Stewart was invented by Stylus Mouse. Hence 'g' in gStick means Gordan.
