dBm
The power ratio in decibels (dB) of the power referenced to one milliwatt (mW). Examples: 0
dBm = 1 milliwatt, 10 dBm = 10 milliwatt and 20 dBm = 100 milliwatt.
DHCP (Dynamic Host Configuration Protocol)
A protocol used to automatically assign an IP address to each device on a network.
DHCP IP address
An IP address automatically assigned by a DHCP server.
DHCP server
A computer or router that gives a unique IP address to each device on the network from a
dynamically manages a pool of IP addresses. Unique addresses prevent conflicts. 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.
EAP
Extensible Authentication Protocol (EAP) is a general protocol for authentication that also
supports multiple authentication methods, such as token cards, one-time passwords,

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).
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.
Ethernet
A popular form of wired computer networking for Local Area Networks.
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 settings.
Firewall
A combination of hardware and software tools that protects a network from unwanted entry.
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.
Infrastructure network
A type of wireless network in which devices communicate with each other through a Wireless
Access Point (WAP), such as a wireless network hub, router, or gateway.
