DHCP Short for Dynamic Host Configuration Protocol, a protocol for assigning
dynamic IP addresses to devices on a network. With dynamic addressing,
a device can have a different IP address every time it connects to the
network. In some systems, the device’s IP address can even change while
it is still connected. DHCP also supports a mix of static and dynamic IP
addresses.
Dynamic addressing simplifies network administration because the
software keeps track of IP addresses rather than requiring an
administrator to manage the task. This means that a new computer can
be added to a network without the hassle of manually assigning it a
unique IP address.
DIMMs Dual In-line Memory Module, a small circuit board that holds memory. A
single in-line memory module (SIMM) has a 32-bit path to the memory,
whereas a DIMM has a 64-bit path.
distinctive ring A feature offered by some telephone companies in Australia, Canada,
New Zealand, the United States, and the United Kingdom that allows two
or three phone numbers to be set up on the same telephone line. Each
phone number has a different ring pattern, and the fax machine can be
configured to recognize the distinctive ring of the fax number.
DLC Short for Data Link Control. Every network interface card has a DLC
address or DLC identifier that uniquely identifies the node on the network.
dots per inch (dpi) A measurement of resolution used for scanning and printing. Generally,
more dots per inch mean a higher resolution, a greater amount of visible
detail in the image, and a larger file size.
EconoMode EconoMode is a toner-saving feature on the HP LaserJet product.
EconoMode reduces the amount of toner on a printed page, so that the
print cartridge lasts longer. The printed result is similar to printing a
document in draft mode.
ECP Extended capabilities port, a parallel-port standard for PCs that supports
bi-directional communication between the PC and attached devices (such
as a printer).
e-mail (electronic mail) An abbreviation for electronic mail. Software that can be used to
electronically transmit items over a communications network.
embedded An object created with one application and embedded into a document
created by another application. Embedding the object, rather than simply
inserting it by pasting it, ensures that the object retains its original format.
The embedded object can be modified with the original program. In
Windows environments, embedding objects is made possible by a
technology called OLE.
Ethernet A common type of local area network recognized as the industry
standard. Ethernet is also known as IEEE 802.3. Information is broken
into “packets” that are transmitted in order until they arrive at the
destination without colliding with any other “packet.” A network node is
either transmitting or receiving a packet at any instant.
expand A process to restore a collapsed sticky note from an icon to its original
size.
fax An abbreviation for facsimile. The electronic encoding of a printed page
and the transmission of the electronic page over a telephone line. The
product software can send items to electronic fax programs, which require
a modem and fax software.
