optical character recognition (OCR) software
OCR software converts an electronic image of text, such as a scanned
document, into a form that word processor, spreadsheet, and database
programs can use.
pixels per inch (ppi)
A measurement of resolution that is used for scanning. Generally, more
pixels per inch result in a higher resolution, more visible detail in the image,
and a larger file size.
printer driver
A printer driver is a program that software programs use to gain access to a
device’s features. A printer driver translates a software program’s formatting
commands (such as page breaks and font selection) into a printer language
(such as PostScript or PCL), and then sends the print file to the device.
private branch exchange (PBX)
A small telephone switching system that typically is used by large
businesses or universities to connect all telephone extensions within the
organization. A PBX also connects to the public switched telephone network
(PSTN) and may be either manual or dial, depending on the method used by
extensions to place incoming or outgoing calls. Normally, the equipment is
owned by the customer rather than leased from the telephone company.
public switched telephone network (PSTN)
The worldwide dial-up telephone network or a portion of that network. Users
are assigned unique phone numbers, which allow them to connect to the
PSTN through local telephone exchange companies. Often, this phrase is
used when referring to data or other non-telephone services carried over a
path initially established using normal telephone signaling and ordinary
switched long-distance telephone circuits.
Readiris
An optical character recognition (OCR) program that was developed by
I.R.I.S. and that is included with the device software.
resolution
The sharpness of an image, measured in dots per inch (dpi). The higher the
dpi, the greater the resolution.
shared line
A single telephone line that is used for both voice and fax calls.
surge protector
A device that protects a power supply and communications lines from
electrical surges.
TWAIN
An industry standard for scanners and software. By using a TWAIN-
compliant scanner with a TWAIN-compliant program, a scan can be initiated
from within the program.
URL
Uniform resource locator, the global address of documents and resources on
the Internet. The first part of the address indicates what protocol to use, the
second part specifies the IP address or the domain name where the
resource is located.
