operating system: A group of programs that controls the basic operation 
of a computer. Operating system functions include interpreting 
programs, creating data files, and controlling the transmission and 
receipt (input/output) of data to and from memory and peripheral 
devices. 
output: The results of a computer operation. Output commonly indicates 
data  
1) printed on paper,  
2) displayed at a terminal,  
3) sent through the serial port of internal modem, or  
4) stored on some magnetic media.

The computer provides various levels of password protection such 
as user, supervisor and eject. 
pel: The smallest area of the display that can be addressed by software. 
Equal in size to a pixel or group of pixels. See pixel. 
peripheral component interconnect: An industry standard 32-bit bus. 
peripheral device: An I/O device that is external to the central processor 
and/or main memory such as a printer or a mouse. 
plug and play: A capability with Windows that enables the system to 
automatically recognize connections of external devices and make 
the necessary configurations in the computer. 
pixel: A picture element. The smallest dot that can be made on a display 
or printer. Also called a pel. 
port: The electrical connection through which the computer sends and 
receives data to and from devices or other computers.

R 
Radio frequency interference (RFI) shield: A metal shield enclosing the 
printed circuit boards of the printer or computer to prevent radio 
and TV interference. All computer equipment generates radio 
frequency signals. The FCC regulates the amount of signals a
