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.
U
Uninstall
To remove software installed on a computer and return the computer to its condition
before the software was installed.
Universal Serial Bus (USB) interface
These are new serial interface standards. This bus automatically recognizes
connections (Plug and Play) to allow plugging and unplugging connectors with the
power still turned on to the PC or peripheral equipment.
V
Virtual Memory
Space on the hard disk that Windows uses for temporary data storage as if it were
actually random access memory (RAM). Windows does this by means of a swap file.
This provides Windows with more usable memory, but reduces speed of access to it
when the swap file must be used. See also Physical RAM.
W
Weight
Refers to the thickness of a font: light, medium, or bold. Also refers to the thickness of
paper.
WIA (Windows Image Acquisition)
Standard for downloading images from scanners or digital cameras. The machine
includes a TWAIN-compliant driver and a WIA-compliant driver. The WIA driver can
only be used with Windows XP. With either driver, you can scan documents with the
machine in applications which support the TWAIN interface (Photoshop etc.).
Windows Explorer
The Windows program you can use to browse through, open, and manage the disk
drives, folders, and files on your computer in a network system. You can also use
Windows Explorer to view and open shared folders on other computers on the
network. You can use Windows Explorer to manage your files by moving, copying,
renaming, and deleting files.
