A mouse and a keyboard are the important parts of a computer. A mouse
is an input device, used to select an object on the monitor. When we move a
mouse, an arrow-like pointer displayed on the monitor also moves. First, let
us learn about mouse.
TYPES OF MOUSE
The different types of computer mouse are:
OPTICAL MOUSE
The optical mouse is the most commonly used mouse. It uses
a laser light to help in moving the pointer on the screen.
GAMING MOUSE
The gaming mouse is generally used to play games. It is similar
to a scroll mouse but works much faster.
WIRELESS MOUSE
A wireless mouse connects to the computer without a wire. It is
also known as a cordless mouse. It uses wireless technology to
send signals to the computer and helps it work.
ACTIONS OF A MOUSE
A mouse is used to perform various actions.
SINGLE-CLICK OR LEFT-CLICK
To left-click a mouse, press the left mouse
button once and then release it. Doing this
makes a click sound. This action is called Click
clicking and it is done to select an item on
the screen.
