DHCP

Dynamic Host Configuration Protocol. A server on the network that supplies

 

configuration parameters to devices on the network. On small networks, this

 

could be a router.

 

 

DNS

Domain Name Service. When you use the Web or send an e-mail message,

 

you use a domain name to do it. For example, the URL http://www.hp.com

 

contains the domain name hp.com. The DNS on the Internet translates the

 

domain name into an IP address. Devices use the IP addresses to refer to

 

one another.

 

 

DNS-SD

See DNS. The SD portion stands for Service Discovery. This is part of a

 

protocol developed by Apple that enables automatic discovery of computers,

 

devices, and services on IP networks.

 

 

DSL

Digital Subscriber Line. A high-speed connection to the Internet.

 

 

Ethernet

The most common local network technology that connects computers using

 

copper cabling.

 

 

Ethernet cable

The cable used to connect network elements in a wired network. The CAT-5

 

Ethernet cable is also known as a straight-through cable. When using an

 

Ethernet cable, the network elements must be attached to a router. An

 

Ethernet cable uses an RJ-45 connector.

 

 

EWS

Embedded Web Server. A browser-based utility that provides a simple way

 

to manage the HP All-in-One. You can monitor status, configure HP All-in-

 

One networking parameters, or access HP All-in-One features.

 

 

Gateway

A computer or other device, such as a router, that serves as an entrance to

 

the Internet or another network.

 

 

HEX

Hexadecimal. The base 16 numbering system, which uses the digits 0-9 plus

 

the letters A-F.

 

 

host computer

The computer at the center of a network.

 

 

Hostname

The TCP/IP name assigned by the installation software to the device. By

 

default, this is the letters HP followed by the last 6 digits of the Media Access

 

Control (MAC) address.

 

 

hub

No longer commonly used in modern home networks, a hub takes its signal

 

from each computer and sends it to all of the other computers connected to

 

the hub. Hubs are passive; other devices on the network plug into the hub in

 

order to communicate with one another. A hub does not manage the network.

 

 

IP address

A number that uniquely identifies the device on the network. IP addresses

 

are assigned dynamically through DHCP or AutoIP. You can also set up a

 

static IP address, though this is not recommended.

 

 

MAC address

Media Access Control (MAC) address that uniquely identifies the HP All-in-

 

One. This is a unique 12-digit identification number assigned to networking

 

hardware for identification. No two pieces of hardware have the same MAC

 

address.

 

 

network name

The SSID or network name identifies a wireless network.

 

 

NIC

Network Interface Card. A card on your computer that provides an Ethernet

 

connection so that you can connect your computer to a network.

 

 

RJ-45 connector

The connector on the ends of an Ethernet cable. Although standard Ethernet

 

cable connectors (RJ-45 connectors) look similar to standard telephone

 

cable connectors, they are not interchangeable. An RJ-45 connector is wider

 

and thicker and always has 8 contacts on the end. A phone connector has

 

between 2 and 6 contacts.
