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
