DHCP (Dynamic Host Configuration Protocol): A protocol used to automatically assign an IP
address to each device on a network.
DHCP server: This server dynamically manages a pool of IP addresses for use on a network or
the Internet. When a user logs in, the server “loans” the user an IP address for the duration of the
network connection. When a user logs off, the IP address is returned to the pool for use by another
device.
Digital Certificate: An electronic means of proving the identity of a network user or device.
Certificates contain detailed information about the user's device in a standard format. Digital
certificates are typically issued by a trusted third-party Certificate Authority (CA). Locally
administered, or self-signed, certificates are valid in some instances.
e
EAP: Extensible Authentication Protocol (EAP) is a general protocol for authentication that also
supports multiple authentication methods, such as token cards, one-time passwords, certificates,
and public key authentication.
Encryption: A network security that encodes the data sent across a wireless network making the
data unintelligible to unauthorized users. The printer supports WEP
and WPA.
Encryption keys: A sequence of characters or digits that a wireless device uses to encode data.
Encryption keys can be static (as they are in WEP) or dynamic (as they are in WPA).
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 used
to connect two devices that have Ethernet ports but that are not hubs or routers. Use a CAT-5
straight-through cable with an RJ-45 plug to connect the printer to an Ethernet network.
EWS (embedded Web server): A server that is completely contained within a device. An EWS
provides management information about the device. This is helpful for managing single devices on
a small network. By using a Web browser to access an EWS, network users can perform such
operations as obtaining network printer status updates, simple troubleshooting, and changing
device configuration setting.
f
Firewall: A combination of hardware and software tools that protects a network from unwanted
entry.
g
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 the network and the
Internet.
h
Host Name: The name by which the printer identifies itself on the network. The printer's host
name appears on the network configuration page. Use the host name to open the printer's
embedded Web server (EWS).
Hub: A simple device that acts as the center of an Ethernet network. Other devices on the network
are connected to the hub.
