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.
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).
