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.
