DHCP is a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, 
a device can have a different IP address every time it connects to the network. In some systems, the device's 
IP address can even change while it is still connected. DHCP also supports a mix of static and dynamic IP 
addresses. Dynamic addressing simplifies network administration because the software tracks IP addresses 
rather than requiring an administrator to manage the task. A new computer can be added to a network 
without the hassle of manually assigning it a unique IP address. 

Extensible Authentication Protocol is a general protocol for authentication that supports multiple 
authentication methods. 
EAP, an extension to PPP, supports such authentication methods as token cards, Kerberos, one-time 
passwords, certificates, public key authentication and smart cards. In wireless communications using EAP, a 
user requests connection to a WLAN through an AP, which then requests the identity of the user and 
transmits that identity to an authentication server such as RADIUS. The server asks the AP for proof of 
identity, which the AP gets from the user and then sends back to the server to complete the authentication. 
EAP is defined by RFC 2284.

The Extended Service Set Identification (ESSID) is a thirty-two character (maximum) alphanumeric key 
identifying the wireless local area network. 

A LAN specification developed jointly by Xerox, Intel and Digital Equipment Corporation. Ethernet 
networks transmit packets at a rate of 10 Mbps.

A local device, usually a router, that connects hosts on a local network to other networks.
