- Primary Storage (Memory)
- Temporarily holds data and program instructions for processing the data.
- Printer
- An output device used to produce hardcopy.
- Printer - bubblejet
- Characters and graphics are printed by firing ink droplets at the paper
from thin nozzles.
- Printer - Character
- A printer that prints one character at a time.
- Printer Classification
- printers are classified by Print Method, Impact or Non-impact, Dot Matrix
or shaped , high or low speed.
- Printer command language (PCL)
- A command set developed by Hewlett-Packard for describing how a laser
printer is to draw a page.
- Printer Controls
- buttons on the printer enabling you to set options (for example; Online,
Form Feed).
- Printer - Dot matrix
- A low speed printer that uses a row of pins hammering a ribbon to produce
characters.
- Printer - Daisy wheel
- exchangeable print heads which look like 60 mm diameter spoked rimless
wheels, with individual characters located sideways on the end of each spoke.
- Printer - -impact
- A printer that uses hammering mechanism as a means of forming a character
image on the paper.
- Printer - - Inkjet
- non-impact character matrix printers which fire ink droplets onto the
paper by using an 'electrostatic field'.
- Printer - - Laser
- A non-impact dot matrix printers using a process similar to that used by
a photocopy machine is used to form a page image on a drum
- Printer - Line
- A printer that prints a line at a time.

- An output device that enables a computers video output to be projected
onto a large screen.
- Protocol
- rules for exchanging data
- Proxy server
- A server that resides between the client and the server, that monitors
