R
Random Access Memory (RAM)
The working memory of the computer in which programs and data
are temporarily stored while you use them. Resetting or shutting
off the computer clears all information from RAM. Printing very
complicated documents might require closing other running
programs or adding more RAM to the computer.
Reinstall
To remove installed software and install again.
Resolution
The density of dots for any given output device, expressed in
terms of dots per inch (dpi). Low resolution causes font
characters and graphics to have a jagged appearance, but prints
faster than higher resolutions. Higher resolution provides
smoother curves and angles as well as a better match to
traditional typeface designs, but prints more slowly. Resolution
values are represented by horizontal data and vertical data, for
example, 600 x 600 dpi.
S
Scanner driver
A program that controls how the computer and scanner interact.
The scanner driver is provided with two drivers: The TWAIN and
the WIA driver (for use with Windows XP).
Scanners and Cameras folder (Scanners and Cameras
Properties dialog box)
The folder or dialog box that contains information about your
imaging devices, such as scanners or cameras.
T
TWAIN (Technology Without Any Interested Name)
Industry-standard protocol for transferring information from
devices such as scanners and digital cameras to a computer.
Industry-standard protocol for an application programming
interface (API) for input devices such as scanners. If both the
device and the application comply with the standard, they will be
compatible regardless of differences in manufacturer or model.
For example, with TWAIN-compatible image-processing software,
you can start the scanner’s TWAIN driver from the software’s
menu, scan the document and return the scanned image to its
original image-processing software.
