The computer mouse is one of the devices that make
the computer so easy to use. It allows you to input data by just moving
your hand and pointing to items on the monitor. There are different
types of mice available. It is up to you to choose the one that
satisfies your requirements, and fits your budget. While most mice are
designed for right-handed people, there are many that are ambidextrous.
Also, there are some mice designed specifically for left-handed people.

that rolls on a surface,
inputting data that moves the cursor on the monitor. It is one of the
earliest styles of mice.
Newer technology is used in the optical
which uses an LED and a photocell to detect mouse movement on a
surface, thereby moving the cursor on the screen.

uses similar technology to the LED mouse, but, replaces the LED with a
laser. This allows greater resolution and more accurate movement of the
cursor. This type of mouse lends itself to graphics and art, which
requires greater accuracy.
The trackball or track ball mouse reduces hand movement
using only the thumb
and finger. It is best used for drawing because of its accuracy.
The USB and PS/2 ports are the two most common
interfaces for the
modern computer mouse. Most desktop computers provide both ports, but
older motherboards may require you to go with the PS/2 port. You will
find most laptop computers do not have a PS/2 port. This requires a
mouse equipped with a USB connector. One of the benefits of the USB
port is hot swapping, this allows you to plug or unplug a mouse when
the computer is running.

physically attached to the computer. The two types of wireless mice are
RF and Bluetooth. The advantage of Bluetooth is longer range and
greater protection from interference.

scrolling. Some mice have one button (Macintosh), while others have
four or five buttons, some of which are programmable. In addition some
of the wheels are capable of tilting sideways for lateral scrolling.

situation. The computer game joystick is one such device. It is used
for computer gaming, and it might be in the shape of an automobile
steering wheel, or an aircraft yoke. Another such device is the rugged
mouse, one that is built to work in very harsh environments,
dirt, and moisture can be present. You can check out some of these
