A framework for intelligently controlling access to computer resources, enforcing policies, auditing usage, and providing the information necessary to bill for services. |
A.A.A - Authentication Authorization and Accounting |
|
|
Specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects |
ACL - Access Control List |
|
|
A data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. |
ADSL - Asymmetric Digital Subscriber Line |
|
|
A specification for the encryption of electronic data based on the Rijndael cipher established by the U.S. National Institute of Standards and Technology (NIST) in 2001. |
AES - Advanced Encryption Standard |
|
|
Guarantees connectionless integrity and data origin authentication of IP packets. Further, it can optionally protect against replay attacks by using the sliding window technique and discarding old packets |
AH - Authentication Header |
|
|
a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave |
AM - Amplitude Modulation |
|
|
a feature of later Windows operating systems where DHCP clients can automatically self-configure an IP address and subnet mask when a DHCP server isn't available. |
APIPA - Automatic Private Internet Protocol Addressing |
|
|
manages the distribution of Internet number resources, including IPv4 and IPv6 address space and AS numbers. |
ARIN - American Registry for Internet Numbers |
|
|
a telecommunication protocol used for resolution of network layer addresses into link layer addresses, a critical function in multiple-access networks. |
ARP - Address Resolution Protocol |
|
|
a collection of connected Internet Protocol (IP) routing prefixes under the control of one or more network operators on behalf of a single administrative entity that presents a common, clearly defined routing policy to the Internet. |
AS - Autonomous System |
|
|
a business providing computer-based services to customers over a network; such as access to a particular software application (such as customer relationship management) using a standard protocol (such as HTTP). |
ASP - Application Service Provider |
|
|
a telecommunications concept defined by ANSI and ITU (formerly CCITT) standards for carriage of a complete range of user traffic, including voice, data, and video signals |
ATM - Asynchronous Transfer Mode |
|
|
A test for the number of received bits of a data stream over a communication channel that have been altered due to noise, interference, distortion or bit synchronization errors. |
BERT - Bit-Error Rate Test |
|
|
a standardized exterior gateway protocol designed to exchange routing and reach-ability information between autonomous systems (AS) on the Internet. |
BGP - Border Gateway Protocol |
|
|
a miniature quick connect/disconnect radio frequency connector used for coaxial cable. |

|
frames that contain information about the Spanning tree protocol (STP). |
BPDU - Bridge Protocol Data Unit |
|
|
an Integrated Services Digital Network (ISDN) configuration intended primarily for use in subscriber lines similar to those that have long been used for voice-grade telephone service. |
BRI - Basic Rate Interface |
|
|
the MAC address of the wireless access point (WAP) generated by combining the 24 bit Organization Unique Identifier (the manufacturer's identity) and the manufacturer's assigned 24-bit identifier for the radio chipset in the WAP. |
BSSID - Basic Service Set Identification
|
|
|
allows several terminals connected to the same multi-point transmission medium to transmit over it and to share its capacity. Examples of shared physical media are wireless networks, bus networks, ring networks and half-duplex point-to-point links. |
