What are different types of computer mouse?
The conventional mouse has a ball at the bottom. The mouse is connected to the computer using a serial or USB cable. The mouse is placed on the mouse pad. When the mouse is moved, the X and Y is calculated and accordingly the cursor will move on the screen. Then the Wireless mouse was introduced since the cable caused many problems But this wireless mouse is not so widely used as it is quite expensive. Then the Optical mouse was introduced since the ball at the bottom caused many problems when dust and dirt accumulates inside. The optical mouse is quite popular as it is more useful and cheaper than the wireless mouse. Scroll mouse is a mouse with a scroll button on top of the mouse which makes scrolling easier.
