G-30 Glossary
page-description language (PDL) A language that communicates to a printer how
printed output should appear. The printer uses the PDL to construct text and graphics
to create the page image. PDLs are like blueprints in that they set parameters and
features such as type sizes and fonts, but leave the drawing to the printer.
page fault An error that occurs when the requested code or data cannot be located
in the physical memory that is available to the requesting process.
paging The process of moving virtual memory back and forth between physical
memory (RAM) and the disk. Paging occurs when physical memory becomes full.
paging file A special file on one or more of the hard disks of a computer running
Windows XP Professional. Windows XP Professional uses virtual memory to store
some of the program code and other information in RAM and to temporarily store
some of the program code and other information on the computer’s hard disks.
This increases the amount of available memory on the computer.
parity An error-checking procedure in which the number of 1s must always be the
same—either odd or even—for each group of bits transmitted without error. Parity
is used for checking data transferred within a computer or between computers.
partition A logical division of a hard disk that functions as if it were a physically separate
unit. Each partition can be formatted for a different file system.
password-protected share Access to a shared resource that is granted when a user
enters the appropriate password.
password reset disk A removable disk on which is stored a file that allows a user to
recover a user account when the user forgets his or her password.
Pathping A command-line tool that is a combination of both Ping and Tracert, displaying
information about packet loss at every router between the host computer
and the remote one.
PCI See Peripheral Component Interconnect (PCI).
PDA See personal digital assistant (PDA).
PDL See page-description language (PDL).
PDN See public data network (PDN).
peer-to-peer network A network in which there are no dedicated servers or hierarchy
among the computers. All computers are equal and therefore known as peers.
Generally, each computer functions as both client and server.
Performance Console A tool that is used to monitor resource usage on a computer
running Windows XP Professional. The Performance Console provides access to
two snap-ins: System Monitor and Performance Logs And Alerts.
Performance Logs And Alerts A snap-in that collects performance data over time
from the local or a remote computer or that has Windows XP alert you when a
particular performance threshold is crossed.
