2. One, Two and Three Buttons Mouse. A mouse can have one, two or three buttons.
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. With a mouse having multiple buttons, the leftmost button is the main button
that allows for most mouse operations because most people are right-handed and use their
right index finger to click the main button. However, another button can always be
configured as the main button. For example, the right-most button can be configured as
the main button for left-handed users.
3. Serial and Bus Mouse. A serial mouse is one, which is designed to plug into a serial
port (a built-in socket in the computer's back panel to which external devices can be
connected). Such a mouse does not require a special electronic card for connecting the
mouse to the computer system. On the other hand, a bus mouse is one that requires a
special electronic card that provides a special port just for the mouse for connecting the
mouse to the computer system. 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...
