Inkjet Printer
Inkjet Printers make less noise because no hammering is done and these have
many styles of printing modes available. Colour printing is also possible. Some
models of Inkjet printers can produce multiple copies of printing also.
Plotter
A plotter is a computer hardware device much like a printer that is used for
printing vector graphics. Instead of toner, plotters use a pen, pencil, marker, or
another writing tool to draw multiple, continuous lines onto paper rather than a
series of dogs like a traditional printer. There are three different types of plotter:
Flatbed Plotters - These hold the paper still while the pens move.
Drum Plotters - These roll the paper over a cylinder.
Pinch-Roller Plotters - These are a mixture of the two types above.

Speaker
A Speaker is used to outputs sound from the computer. It helps us hear the sound
when we play music or watch movies on our computer. Some computers come
with in-built speakers whiles others are not. Most laptops come with in-built
speakers.
