DHCP

Dynamic Host Configuration Protocol

A protocol used for automatically fetching communica-
tion parameters such as IP addresses. The side which
assigns IP address is called DHCP server and the side
that is assigned it is called DHCP client.

DIMM

Dual-in-line memory module.

Disk

A spinning platter of magnetic data storage media. If the
platter is very stiff it is a hard drive, if it is highly flexible
it is a floppy disk, if it is a floppy disk in a hard housing
with a shutter it is commonly called a diskette.

Disk Drive

The hardware which spins the disk and has the heads
and control circuitry for reading and writing the data
on the disk.

Diskette

A floppy disk in a hard housing with a shutter.

DMA

Direct Memory Access

Special circuitry for memory to memory transfers of
data which do not require CPU action.

DMI

Desktop Management Interface

A standard that provides PC management applications
with a common method of locally or remotely querying
and configuring PC computer systems, hardware and
software components, and peripherals.

DNS

Domain Name System

A function that controls the correspondence of IP
addresses assigned to a computer with the name. Even
for those computers whose IP addresses are unknown, if
their names are known, it is possible to communicate
with them.

DOS

Disk Operating System (MS-DOS is a Microsoft Disk
Operating System).

Driver

A computer program which converts application and
operating system commands to external devices into the
exact form required by a specific brand and model of
device in order to produce the desired results from that
particular equipment.

ECP

Extended Capability Port. A set of standards for high
speed data communication and interconnection
between electronic devices.

Encryption Key (Network Key)

Key information used to encode data for data transfer.

This device uses the same encryption key to encode and
decode the data, and the identical encryption key is
required between the sender and receiver.

ESD

Electro-Static Discharge. The sudden discharge of elec-
tricity from a static charge which has built-up slowly.
Example: the shock you get from a doorknob on a dry
day or the sparks you get from brushing hair on a dry
day.

Extended Memory

All memory more than the 640KB recognized by
MS-DOS as system memory.

FCC

Federal Communication Commission.

Floppy Disk

A spinning platter of magnetic data storage media which
is highly flexible.

Gigabyte.

Hard drive

A spinning platter of magnetic data storage media where
the platter is very stiff.

I/O

Input/Output. Data entering and leaving your notebook
in electronic form.

I/O Port

The connector and associated control circuits for data
entering and leaving your notebook in electronic form.

IDE

Intelligent Drive Electronics. A type of control interface
for a hard drive which is inside the hard drive unit.

IEEE 1394

Industry standard that allows you to connect between
your notebook and a peripheral device such as a digital
camera. Also known as “Firewire” or “iLINK”.
