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.
