people find it comfortable to place the keyboard on the desk directly in front
of them and the mouse to one side of the keyboard.(we discuss about Input device in other blog.)
The mouse controls the pointer on the screen. Whenever you
move the mouse across the desk, the pointer will move in a similar manner.
A
mouse usually has two buttons, which are referred to as the left button and the
right button. You will often interact with the computer by moving the mouse
pointer over something on the computer screen, then clicking one of the
buttons.

into the computer. Whenever you see a flashing vertical line—called the
cursor—you can start typing.
