AAC - Advanced Audio Coding - audio compression technology
that is part of the MPEG-2 standard - available in three profiles:
Main, Low Complexity (LC) and Scaleable Sampling Rate (SSR), with
Main providing the highest quality
AAL - ATM Adaption Layer - The part of the ATM protocol
that breaks up application packets into 48-byte payloads which become
ATM cells when the 5-byte headers are attached. The AAL resides
between the higher layer transport protocols and the ATM layer.
The AAL is comprised of two layers: Convergence Sublayer (CS) and
Segmentation & Reassembly Sublayer (SAR)
ACPI - Advanced Configuration and Power Interface
- power management specification developed by Intel, Microsoft,
and Toshiba. It enables the operating system to control the amount
of power given to each device attached to the computer
ADO - Active Data Objects - programming interface
from Microsoft that is designed as the Microsoft standard for data
access. First used with Internet Information Server, it is expected
to become available for all Microsoft programming languages and
applications
ADSL - Asymmetric Digital Subscriber Line - shares
the same line as the telephone, because it uses higher frequencies
than the voice band - but a POTS splitter must be installed on the
customer's premises to separate the line between voice and ADSL
(a version of ADSL, known as G.lite, Universal ADSL, ADSL Lite and
splitterless ADSL, is geared to the consumer and eliminates the
splitter, but all phones on the line must plug into low-pass filters
to isolate them from the higher ADSL frequencies)
AGP - Accelerated Graphics Port - bus specification
that enables 3D graphics to display quickly on ordinary PCs
AIN - Advanced Intelligent Network - enables service
providers to define, test and introduce new multimedia messaing,
PCS, and cell routing (introduced by AT&T Network Systems in
1991)
AMD - Advanced Micro Devices - a manufacturer of chips
for PCs
AMPS - Advanced Mobile Phone Service - the original
analog cellular network - currently the world's largest cellular
standard (7/29/99)
AMS - Analog and Mixed Signal
ANSI - American National Standards Institute - fosters
the development of technology standards in the United States. www.ansi.org
APEC - Asia-Pacific Economic Cooperation - an interational
organization for promoting open trade and economic cooperation among
21 member economies around the Pacific Rim. www.apec.org
API - Application Programming Interface - clearly
defined interface that lets a programmer control the software for
which the interface was written
APII - Asia-Pacific Information Infrastructure
AQR - Assured Quality Routing
ARIB - Association of Radio Industries and Businesses
- sets the standards for third generation devices (cellular) in
Japan. www.arib.or.jp
ARM - Advanced RISC Machines
ARP - Address Resolution Protocol - a protocol used
to determine the hardware address from the IP address of the destination
computer
ARPU - Average Revenue Per Unit - one indicator of
a wireless business' operating performance. ARPU measures the average
monthly revenue generated for each customer unit, such as a cellular
phone or pager, that a carrier has in operation.
AS/400 - Application System/400 - IBM minicomputer

It is IBM's midrange series of computer systems used primarily for
business applications, most of which are written in RPG III and
COBOL
ASC - Application Solution Centers
ASCII - American Standard Code for Information Interchange
- most common format for text files in computers and on the Internet,
each alphabetic, numeric, or special character is represented with
a 7-bit binary number (string of 0s or 1s)
ASIC - Application Specific Integrated Circuit - chip
that is custom designed for a specific application (rather than
a general purpose chip such as a microprocessor).
ASP - Active Server Pages - a server-side scripting
platform supported by Microsoft Internet Information Server (IIS)
that provides the same functionality as CGI scripts and is useful
for integrating data from Windows-based databases and other ODBC
(Open Database Connectivity) compliant databases with a Web site
ASP - Application Service Providers - service firms
that provide a contractual service offering to deploy, host, manage,
and lease software from a centrally managed facility
ATA - Advanced Technology Attachment - the official
name that the ANSI group X3T10 uses for what the computer industry
calls IDE (Integrated Drive Electronics)
ATM - Asynchronous Tranfer Mode - network technology
for both LANs and WANs that supports realtime voice and video as
well as data. The topology uses switches that establish a logical
circuit from end to end, which guarantees quality of service (QoS)
ATSC - Advanced TV Systems Committee - International
organization that develops voluntary technical standards for advanced
television systems. ATSC Digital TV Standards include HDTV, SDTV,
data broadcasting, multichannel surround-sound audio, and satellite
direct-to-home broadcasting. www.atsc.org
ATVEF - Advanced Television Enhanced Forum - a cross-industry
group formed to define standard protocols for television programs
enhanced with data. www.atvef.com
