ethernet glossary

10/100 Base-T

: A technical term for "ethernet." 10/100 refers to the speed at which the

ethernet network functions. 10 indicates 10 megabits per second (

Mb/s

) for normal Ethernet,

and 100 indicates 100

Mb/s

for Fast Ethernet.

AutoIP

: A process by which a device on a network automatically assigns

IP addresses

to itself.

Broadcast packet

: A

packet

sent from one device on a network to all devices on the network.

DHCP (Dynamic Host Configuration Protocol)

: A

protocol

used to automatically assign an IP

address to each device on a network.

Ethernet

: A popular form of wired computer networking for

Local Area Networks

.

Ethernet cable

: There are two types of ethernet cables. A straight-through cable is the most

common and is used to connect devices on a network to a

hub

or

router

. A crossover cable is a

twisted pair patch cable the routes the transmit signals from one device to the receive signals of

another device. Use an unshielded CAT-5 straight-through cable with an

RJ-45

plug to connect

the printer to an ethernet network.

Gateway

: A dedicated device (

router

or computer) that connects two different networks. For

example, a computer on an ethernet network may act as a gateway between a network and the

Internet.

Firewall

: A combination of hardware and software that protects a network from unwanted entry.

Hub

: A simple device that acts as the center of an ethernet network. Other devices on the

network are connected to the hub.

ICS (Internet Connection Sharing)

: A Windows program that allows a computer to act as a

gateway

between the Internet and a LAN. ICS uses

DHCP

to assign

IP addresses

. See Windows

documentation for more information about ICS.

IP address (Internet Protocol address)

: A unique number that identifies a device on a LAN.

The IP address is often automatically assigned by

DHCP

or

AutoIP

. However, a device can be

manually assigned a

static IP address

.

LAN (Local Area Network)

: A high-speed type of computer network that connects devices that

are a relatively short distance from one another. Ethernet is one type of LAN.

MAC address (Media Access Control address)

: The hardware address for a device on a

network. The printer's MAC address appears on the network configuration page and on the label

near the printer's ethernet port.

Mb/s (megabits per second)

: The measure for the rate at which an ethernet network

functions. For example, 1 Mb/s equals 1,000,000 bits per second (or 125,000 bytes per second).

Network Name

: The name by which the printer identifies itself on the network (also known as

the printer's "friendly name"). The printer's Network Name is item 1 on the

network configuration

page

. Use the Network Name to open the printer's

internal web page

.

Packet

: A message sent from one device on a network to other devices on the network.

ethernet glossary

Protocol

: A "language" that devices on a network use to communicate with each other. A

popular network protocol is

TCP/IP

.

RJ-45

: The type of plug at the end of an ethernet cable.

Router

: A complex internetworking device that directs packets from one network to another

network. A router can act as a gateway between a

LAN

and the Internet.

Static IP address

: An

IP address

that is manually assigned to a device on a network. A static IP

address remains fixed until changed manually. Alternative methods for assigning IP address are

DHCP

and

AutoIP

.

Subnet

: A "small network" that acts as part of a large network. It is recommended that the

printer and the computers that use it all be on the same subnet.

Subnet mask

: A number that identifies what

subnet

an

IP address

belongs to.

TCP/IP (Transmission Control Protocol/Internet Protocol)

: The network communication

protocol

used on the Internet. The printer's built-in ethernet feature supports LANs that use

TCP/IP.

Unicast packet

: A

packet

sent from one device on a network to another device on the network.
