of Defense to support the internetworking of dissimilar computers across a network. IP is
perhaps the most important of the protocols on which the Internet is based. It is the standard
that describes software that keeps track of the internetwork addresses for different nodes,
routes, and outgoing/incoming messages on a network. Some examples of IP applications
include email, chat, and web browsers.
IP address
Internet protocol address. A 32-bit sequence of numbers used for routing IP data. Each IP
address identifies a specific component on a specific network. The address contains a network
address identifier and a host identifier.
ISO
International Organization for Standardization. An international body that defines global
standards for electronic and other industries.
P
PC
personal computer.
Q
QAM
quadrature amplitude modulation. An amplitude and phase modulation technique for
representing digital information and transmitting that data with minimal bandwidth. Both
phase and amplitude of carrier waves are altered to represent the binary code. By
manipulating two factors, more discrete digital states are possible and therefore larger binary
schemes can be represented.
R
RADIUS
Remote Authentication Dial-In User Service. A networking protocol that provides centralized
Authentication, Authorization and Accounting (AAA) management for computers to connect
and use a network service.
RF
radio frequency. The frequency in the portion of the electromagnetic spectrum that is above
the audio frequencies and below the infrared frequencies, used in radio transmission systems.
RMA
return material authorization. A form used to return products.
RPU
Remote Provisioning Utility.
