An output device is hardware that receives data from a computer and converts it into a human-perceptible form, with examples including monitors, printers, speakers, plotters, and projectors. Monitors display images using pixels, while printers can be impact or non-impact types, producing text and graphics on paper. Speakers generate sound from the computer's sound card and projectors display images onto surfaces for larger viewing.

6.  Impact printers
Impact printers print the characters by the by striking them on the ribbon,
which is then pressed on the paper.
 Non- impact printers
Non-impact printers print the characters without using the ribbon. These
printers print a complete page at a time, thus they are also called as page
printers.

There are two types of printers

7.  A computer speaker is an output hardware device that
connects to a computer to generate sound. The signal
used to produce the sound that comes from a
computer speaker is created by the computer's sound
card.

onto is large, flat, and lightly colored.
