R
RAM
(random-access memory):
Temporary storage built into a computer system that functions as a
"workspace" for data and program instructions.
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.
RBOC : Regional Bell
Operating Company.

Real-time
communication: Communication in which information is received at (or nearly
at) the instant it's sent. Real-time communication is a characteristic of
synchronous learning.
RealAudio:
RealAudio is a method for delivering continuous or "streaming" sound to a
user, rather than require the user to download the entire file before
listening to it. RealAudio requires special software to receive and play the
sounds. Many radio stations and some television stations offer RealAudio
broadcasts of their programming.
Receive site: A location that can receive transmissions from
another site for distance learning.
Repurpose:
To reuse content by revising or restructuring it for a different purpose
than it was originally intended or in a different way.
Resolution: The clarity of the image on the video display screen.

Reusable:
E-learning content that can be transferred
to various infrastructures or delivery mechanisms, usually without
changes.
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.
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 for a record or group of records in the registry.
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.
resolver :
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
RFP (request
for proposal): A document produced by a company seeking goods or services and
distributed to prospective suppliers. Suppliers then provide proposals based
on the criteria specified within the RFP.
RIO
(reusable information object):
A collection of
content, practice, and assessment items assembled around a single learning
objective. RIOs are built from templates based on whether the goal is to
communicate a concept, fact, process, principle, or procedure. (Pronounced
"REE-O")

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.
RLO
(reusable learning object):
A collection of RIOs, overview, summary, and assessments that supports a
specific learning objective. (Pronounced "R-L-O")
robot :
A fast, automated program, such as a search engine, indexing program, or
cataloging software, that requests Web pages much faster than humans can.
ROI (return
on investment):
Generally, a ratio of the benefit or profit received from a given
investment to the cost of the investment itself. In e-learning, ROI is most
often calculated by comparing the tangible results of training (for example,
an increase in units produced or a decrease in error rate) to the cost of
providing the training.

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.
Role play:
(noun) A training technique in which learners act out characters in order to
try out behaviors, practice interactions, communicate for a desired outcome,
and/or solve a dynamic problem. Role plays can reinforce learning and help
people apply new information, skills, and techniques. (verb) To participate
in a role play.
Routing Information Protocol (RIP) :
A protocol that determines the best path for routing traffic over a
network.
RPI : Rockwell
Protocol Interface. A type of HSP modem that is limited to 14.4
connections.

run-time object :
An object created at run time and used as part of an executable
application. See also design-time object.
