Read the given paragraph carefully and answer the
given questions in short.
A mouse is an input pointing device. It is also called
a handheld device. It can fit on your palm very easily.
It was developed by Douglas Engelbart in 1964 AD. It
has two or three buttons. Traditional mouse has two
buttons but the latest mouse has three buttons with
scroll button. The two mouse buttons are left mouse
button and right mouse button. The optical mouse
with laser technology is more popular these days. To
work smoothly with the desktop computer, mouse is
essential. You can work with the laptop even without
mouse. Instead of using mouse, you can use touch pad
in laptops.
