RAM (Random Access Memory)
The place in your computer that programs
reside when running. You can access any part of the memory, and
it can easily be overwritter with new values.
rar (.rar)
This is the file extension of a type of
compressed file created by the WinRAR program by RarSoft. It is
considered by many to be more versatile than other compression programs
on the market such as WinZip.
Raster Graphics
This form of graphics is probably what
you are looking at now. Composed of pixels on a bitmap, it allows
for solid colored objects and graphics as we know them. See also
vector graphics.
Real-time
Real-time refers to tasks that are time
critical and must happen in our time. Real-time is the highest priority
you can give to a thread or process in the Windows environment.
Even though this is accounted for in the operating systems, Windows
is a poor real-time OS. The user interface should always be real-time.
If you move the mouse, your pointer should move on screen immediately.
Unfortunately, Windows can bog down enough so that this doesn't
happen. Other real-time applications can include medical applications
and control of real world systems. For example, you want to make
sure that the train switches tracks on time and not too late because
your server is bogged down.
Rendering (or Shading)
Determines how colors are used on each
triangle.
Results Ranking
The order in which search results appear. How often your terms occur
in documents and whether in title or how near the top of the text.
Ranking is automatic in almost all systems.
RGB (Red-Green-Blue)
CRT monitors, including television sets,
use red, green and blue light to represent the entire color spectrum.
When you put red, green and blue light together, you get white light.
This is ideal for representing images on the black screen. Most
graphics programs will let you create colors by setting levels of
red, grean and blue. See also CMYK.
Robot
A Web agent that visits sites to extract data from the site. Most
commonly, data from robots is used to build the catalogs for search
engines.
