Technology [P-S]
QuickTime VR (QTVR)
A part of the QuickTime architecture that allows 360-degree interactive panoramas to be developed and viewed. (VR = virtual reality)
RAM (Random Access Memory)
Temporary storage built into a computer system that functions as a "workspace" for data and program instructions.
Raster graphic
A computer image made up of a collection of dots. Can become ragged or otherwise distorted when the image is enlarged or shrunk.
RealMedia
One of the first CODECs for delivering streaming video over the Internet. Like other CODECs, RealMedia (comprised of RealVideo, RealAudio, and other file formats created by Real) use compression algorithms for eliminating data that can be considered as extraneous or not as important as other information. RealMedia and Windows Media are the two most widely used technologies for streaming video today.
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.
Repurpose
To reuse content by revising or restructuring it in a different way or for a different purpose than it was originally intended.
Resolution
The number of pixels in a given space, usually measured as dots per inch (DPI). Also, the number of dots per inch used by an output device.
Reusable
E-learning content that can be transferred to various infrastructures or delivery mechanisms, usually without changes.
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 in 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")
RLO (Reusable Learning Object)
A collection of RIOs, overview, summary, and assessments that supports a specific learning objective. (Pronounced "R-L-O")
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.
RSS (Real Simple Syndication)
RSS, a lso know as Rich Site Summary, is an XML format for distributing news headlines on the Web, also known as syndication. First started by Netscape as part of the My Netscape site.
Scalability
The degree to which a computer application or component can be expanded in size, volume, or number of users served and continue to function properly.
Scanner
A device that converts a printed page or image into an digital representation that can be viewed and manipulated on a computer.
SCORM (Sharable Content Object Reference Model)
A set of specifications that, when applied to course content, produces small, reusable learning objects. A result of the Department of Defense's Advance Distributed Learning (ADL) initiative, SCORM-compliant courseware elements can be easily merged with other compliant elements to produce a highly modular repository of training materials.
Screen reader
Computer software that reads aloud text on the screen. Often used by individuals who are visually impaired.
Screenshot
A picture of a computer display that shows the display at a given point in time. Also called a screen capture. Annotated screenshots are often used in training programs and to illustrate software manuals.
Scroll
To move text and images on a computer screen in a constant direction--down/up, or right/left.
Section 508
The section of the 1998 Rehabilitation Act that states that all electronic and information technology procured, used, or developed by the federal government after June 25, 2001, must be accessible to people with disabilities. Affected technology includes hardware such as copiers, fax machines, telephones, and other electronic devices as well as application software and web sites.
Self-assessment
The process by which the learner determines his or her personal level of knowledge and skills.
Self-paced learning
An offering in which the learner determines the pace and timing of content delivery.
Semantic Web, The
The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries. It is a collaborative effort led by W3C with participation from a large number of researchers and industrial partners. It is based on the Resource Description Framework (RDF), which integrates a variety of applications using XML for syntax and URIs for naming. A concept proposed by World Wide Web inventor Tim Berners-Lee.
