Raster fonts
Fonts stored
in files as bitmaps and rendered as an array of dots for displaying
on the screen and printing on paper. Raster fonts cannot be cleanly
scaled or rotated.
Real mode
The backward-compatible
mode of the Intel 80386 family. In real mode, all of the CPU's
protection features are disabled, paging is not supported, and
program addresses correspond to physical memory addresses. The
address space is limited to 1 MB of physical memory and uses
a memory segmentation scheme. Real mode is compatible with 8086,
the 8088, the 80186, and the real mode of the 80286.
Redirector
Networking software
that accepts I/O requests for remote files, named pipes, or
mailslots and then sends (redirects) them to a network service
on another computer. Redirectors (also called network clients)
are implemented as file system drivers in Windows 98.
Registry
The database
repository for information about a computer's configuration.
The registry supersedes use of separate INI files for all system
components and applications that know how to store values in
the registry.
Registry Checker
A system maintenance
program that finds and fixes registry problems and backs up
the registry.
Registry Editor
An application
that is used to view and edit entries in the registry.
Registry key
An identifier

Remote Access Service
(RAS)
A service that
provides remote networking for telecommuters, mobile workers,
and system administrators who monitor and manage servers at multiple
branch offices.
Remote administration
Administration
of one computer by an administrator located at another computer
and connected to the first computer across the network.
Remote procedure call
(RPC)
A message-passing
facility that allows a distributed program to call services available
on various computers in a network. Used during remote administration
of computers, RPC provides a procedural view, rather than a transport-centered
view, of networked operations.
Request for Comments
(RFC)
An official document
of the Internet Engineering Task Force (IETF) that specifies
the details for protocols included in the TCP/IP family.
Resolve
Under DNS, a
client that queries the name server across the network to gain
information about the domain name space.
Resource reservation
protocol (RSVP)
A signaling protocol
that is used to establish connections with the QoS requested
by an application
RFC
See Request for
Comments.
RIP
See Routing Information
Protocol.
RIP listening
A process in
which a computer listens in on RIP packets and adds information
gleaned from those packets to add entries to the route table.
Also called silent RIP.
Robot
A fast, automated
program, such as a search engine, indexing program, or cataloging
software, that requests Web pages much faster than humans can.
Root directory
A specific area
set aside to store boot files and directories.
Route table
A table that
is used to determine where a computer routes packets.
