As many programs are designed to use only a single button, so a one-button mouse is good enough for them. Some programs are designed to operate with a two-button or three-button mouse. If the system has lesser number of buttons, then such programs can still be made to run on the system by providing an alternative way to indicate a click of these buttons - such as by pressing the shift key on the keyboard while the mouse button is clicked.

The special electronic card is fitted into one of the expansion slots inside the computer. Thus a bus mouse occupies one of the expansion slots whereas a serial mouse does not need any expansion slot. 4. Wired and Cordless Mouse. A wired mouse is connected to the computer system with a small cord (wire). On the other hand, a cordless mouse is not connected to the computer system. It communicates with the computer system with the help of a special controller that operates by transmitting a low-intensity radio or infrared signal. Although a cordless mouse is more expensive than a wired mouse, it...
