DNS Domain name service. An internet service
that translates domain names such as
www.nokia.com into IP addresses such as
192.100.124.195. Domain names are easier

because the internet is based on IP
addresses.

system is used by touch-tone telephones.
DTMF assigns a specific frequency, or tone,

by a microprocessor. DTMF tones allow you
to communicate with voice mailboxes,
computerised telephony systems, and so
on.

plug-ins are used in wireless networks to
authenticate wireless devices and
