DHCP*
A utility that enables a server to dynamically assign IP addresses from a
predefined list and limit their time of use so that they can be reassigned.
Without DHCP, an IT Manager would have to manually enter in all the IP
addresses of all the computers on the network. When DHCP is used, whenever
a computer logs onto the network, it automatically gets an IP address assigned
to it.
Diversity antenna*
A type of antenna system that uses two antennas to maximize reception and
transmission quality and reduce interference.
DNS*
A program that translates URLs to IP addresses by accessing a database
maintained on a collection of Internet servers. The program works behind the
scenes to facilitate surfing the Web with alpha versus numeric addresses. A
DNS server converts a name like mywebsite.com to a series of numbers like
107.22.55.26. Every website has its own specific IP address on the Internet.
DoS
Denial of Service.
EAP
(Extensible Authentication Protocol) is a general protocol for PPP
authentication which supports multiple authentication mechanisms.
EAP-TLS
(EAP-Transport Level Security) is used in certificate-based security
environments. It provides the strongest authentication and key determination
method. EAP-TLS provides mutual authentication, negotiation of the
encryption method, and encrypted key determination between the client and
the authenticator.
EAP-TTLS
(EAP- Tunnelled TLS Authentication Protocol) is an EAP protocol that extends
EAP-TLS. In EAP-TLS, a TLS handshake is used to mutually authenticate a
client and server. EAP-TTLS extends this authentication negotiation by using
the secure connection established by the TLS handshake to exchange
additional information between client and server. In EAP-TTLS, the TLS
handshake may be mutual; or it may be one-way, in which only the server is
authenticated to the client.
