Serial Device
A device that is designed to be connected to the serial port. Examples include external modems, digital
cameras, mice, digital notepads, etc.
Serial Port
Also called a Comport. This connection is often 9-pin or 25-pin and generally a male connector. The signal
from the computer is in a serial stream to the attached device. Generally only one serial device can be
attached to a serial port.
SMTP
Simple Mail Transfer Protocol, a communications protocol that directs email exchanges on TCP/IP networks.
SPP
Standard Parallel Port mode. This is the most basic of parallel port modes and is included on most older
computers. This is also the slowest of all the parallel port modes.
Swap File
The area used by virtual memory when the computer runs out of real memory. Heavy imaging work, such as
scanning high-resolution images, may require a large swap file in addition to large amounts of RAM (real
memory).
TrueColor
Graphics mode with 16.7 million colors (24 or 32 bits per pixel). In this mode, the color information saved in
the display memory is not translated by a look-up table, but passed directly to the D/A converter. This means
that the full color information has to be saved for each pixel.
TWAIN
Technology Without An Interesting Name. TWAIN refers to an industry standard that has been developed for
scanning or other external imaging devices to communicate with the computer. All Info ImageReader
scanners are TWAIN-compliant.
VGA
Abbreviation of IBM Video Graphics Adapter, a display adapter with a standard resolution of 640 x 480 with
16 colors.
Virtual Memory
Space on your hard drive that Windows can use as if it is RAM. Windows will “swap” information into and
out of a swap file to allow you to run more programs or tasks on your computer than you would be able to if
you were limited to the memory in your RAM. However, a large swap file does take up hard drive space that
you may need to store programs or data and using virtual memory is slower than using actual RAM.
VRAM
Video Random Access Memory, a fast type of RAM used as display memory on high-end graphics boards.
World Wide Web
An Internet protocol suite that allows the transmission of images, text, files, and multimedia elements that can
be viewed in real-time with a Web Browser (such as Microsoft InternetExplorer or Netscape Navigator).
YCbCr
A color coordinate system used in the JPEG and MPEG standards. The color information is saved in the
