A | B | C | D | E | F | G | H |
---|---|---|---|---|---|---|---|
I | J+K | L | M | N | O | P | Q |
R | S | T | U | V | W | X+Y+Z |
R AD | Rapid Application Development (software development with the use of pre-designed controls and features so that the developer puts the blocks together as opposed to manufacture the block before starting to build). |
RAID | Redundant Array of Independent Disks (hardware or software based system that allows several hard drives to work together so it may appear as a single disk; also, may be used as a spray to get rid of all the "bugs" in your computer) |
RAM | Read or Random-Access Memory--The temporary memory a computer uses to store data currently being used. Unless saved, data in RAM are lost when the computer is turned off. RAM size determines the speed, and number of applications that may run simultaneously (systems with 64 MB or larger RAMs have a reduced need to access the hard drive). |
RAMDAC | RAM-based Digital-to-Analog Converter converts RGB (colors) digital images into an analog signal that the monitor can understand. |
RAP | Regional Access Point (also see NAP [Network Access Point]) |
ratio sites | MP3 sites that require a logged (connected to the site via internet connection) user to upload a certain number of bytes in exchange for "download credits." For example, a site that requires a 1:2 ratio would expect an upload of one byte for each two downloaded bytes. |
REP | Regional Exchange Point (also see NAP [Network Access Point]) |
RAS | Remote Access Service (Networking) |
Raster Graphics | Electron beam that creates a tight sequence of lines on the TV screen. |
RCD | Recordable CD-ROM (used for data archiving/backup, as well as for testing and creating multimedia titles and presentations) |
RDBMS | Relational Data Base Management Systems |
RDC | Remote Data Control |
RDF | Resource Definition Format (a data-modeling language that utilizes XML [Extended Markup Language] syntax) |
RDO | Remote Data Access Object |
RDS | Remote Document Server |
Refresh Rate | is the amount of time it takes for the screen to redraw or the rate of monitor redrawing of its content per minute; a rate of 70 Hz or better is considered desirable and reflects ergonomic concerns regarding screen flicker and eye fatigue. |
Rehabili- tation Act (Section 508 of the) | Federal regulations specifically setting out guidelines for accessible Internet content for individuals with disabilities. A website may be tested for "Section 508" compliance by submitting the site’s URL to http://bobby.watchfire.com/. The Bobby website tests web pages using the guidelines established by the World Wide Web Consortium's (W3C) Web Access Initiative (WAI) as well as Section 508 guidelines from the Architectural and Transportation Barriers Compliance Board (Access Board) of the U.S. Federal Government. |
.rem | REMarks file extension (also, Rapid Eye Movement during sleep in front of your PC) |
REt | Resolution Enhancement (HP Laser printers feature that produces sharp graphic images by the elimination of stair-stepping & jagged edges). |
RFC | Request for Comment (Internet standards) |
RFD | Request for Discussion (Internet process for the formation of additional news groups) |
RFI | Radio Frequency Interference (Electrical noise that distorts radio reception) |
RGB | Red, Green, & Blue digital format screen images are the only analog format a monitor understands. An RGB color definition specifies the relative intensity of each of the three colors which in turn creates a new specific color. Each color has an integer ranging from 0-255 that represents the intensity of that color. |
RIAA | Recording Industry Association of America |
Ring Network | All computers in a ring network are connected in a circle (ring) so that each machine, for example, is wired to two other computers. Ring networks allow the creation of a distributed data processing system, i.e., each machine may operate independently and at the same time share information and resources with other network computers. |
RIP | Routing Internet Protocol (for now Rest In Peace comes later, hopefully, much later...) |
RIPEM | Riordan's Privacy Enhanced Mail |
RISC | Reduced-Instruction-Set Computer |
RJ--45 connector | End of Cat [Category] 5 cable that fits in RJ--45 port |
RJ--45 port | Network interface that connects two PCs via Cat [Category] 5 cable so that resources may be shared between the connected PCs. |
RLL | Run Length Limited (Disk) |
RmDIR | Remove Directory (DOS command to erase an existing directory on a hard drive--if you're still using DOS consider adding a window to your cave...). |
RMF | Rich Music Format (also see MIDI, MOD, WAV, AIFF, & AU) |
RMON | Remote Network Monitoring |
ROFL | Rolling on the floor laughing (E-mail acronym to speed up e-mail message writing) |
ROI |
Return on Investment (term used in discussion on PC upgrades)
NPV -- Net Present Value ROI Formulas: (From PC Computing Nov. 1994, by Ron White, pp. 196-198) Time for upgrade to pay for itself: Time = Cost/(Hours You Use a PC X Salary X Productivity Increase) Productive Hours Gained after one year: Hours Gained = 12 X (Hours You Use PC X Productivity Increase per month) |
Rollover | Multi-line phone connection that automatically routes calls to the next available modem line. |
RPCs | Remote Procedure Calls |
RPM | Revolutions per Minute or Relative Performance Measurement of a PC and its devices that indicates relative performance as compared to a common reference. |
RSAC | Recreational Software Advisory Council |
.rtf | Rich Text Format file extension (a safe text format for FTP [File Transfer Protocol] in MIME [Multiporpose Internet Mail Extention). |
RTM | Radio Telemetry Modul (transmission of race car engine information to race car team by Delphi). |
RTP | Realtime Transport Protocol (Beats Retention, Tenure, Promotion anyday...). |
RTS | Request To Send (or CTS Clear to Send) |
RTSP | Real Time Streaming Protocol |
RTTI | RunTime Type Iinformation (Visual C++ 4.0) |
