ACL

Access Control List: A list of permissions attached to an object, which specifies who or what is allowed to access the object and what operations are allowed to be performed on the object.

AD

Active Directory: An implementation of LDAP directory services by Microsoft for use primarily in Windows environments.

ADMT

Active Directory Migration Tool: The Active Directory Migration Tool version 3 (ADMT v3) provides an integrated toolset to facilitate migration and restructuring tasks in an Active Directory infrastructure.

ADSI

Active Directory Service Interfaces: A set of COM interfaces used to access the features of directory services from different network providers. ADSI is used in a distributed computing environment to present a single set of directory service interfaces for managing network resources. Administrators and developers can use ADSI services to enumerate and manage the resources in a directory service, no matter which network environment contains the resource.

ADSI enables common administrative tasks, such as adding new users, managing printers, and locating resources in a distributed computing environment.

ADSL

Asymmetric Digital Subscriber Line: A form of DSL, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. It does this by utilizing frequencies that are not used by a voice telephone call. A splitter – or microfilter – allows a single telephone connection to be used for both ADSL service and voice calls at the same time. Because phone lines vary in quality and were not originally engineered with DSL in mind, it can generally only be used over short distances, typically less than 4km.

AES

Advanced Encryption Standard: A block cipher adopted as an encryption standard by the U.S. government, also known as Rijndael.

AGPM

Advanced Group Policy Management: Microsoft Advanced Group Policy Management makes it easier for IT organizations to keep enterprise-wide desktop configurations up to date, enabling greater control, less downtime, and reduced total cost of ownership (TCO).

AHCI

Advanced Host Controller Interface: A hardware mechanism that allows software to communicate with Serial ATA devices such as host bus adapters which are designed to offer features not offered by Parallel ATA controllers besides higher speeds, such as hot-plugging and native command queuing.

AIS

Application Information Service: A service in Windows Vista. See Vista’s Application Information Service

ALG

Application Layer Gateway: A service in Windows Vista. See Vista’s Application Layer Gateway Service

AP

Access Point: A device that connects wireless communication devices together to form a wireless network.

APO

Audio Processing Object: Audio processing which can be inserted in the sound stream to modify it. There are two types of APO: GFX (Global) LFX (Local).

ASIO

Audio Stream Input/Output: A computer soundcard driver protocol for digital audio specified by Steinberg, providing a low-latency and high fidelity interface between a software application and a computer’s sound card. Whereas Microsoft’s DirectSound is commonly used as a stereo input and output for non-professional users, ASIO allows musicians and sound engineers to process their audio via Windows’ computer software instead of external hardware.

ASPM

Active State Power Management: Allows power to be incrementally reduced to individual serial links in a PCI Express fabric as a link becomes less active.

ATL

Active Template Library: A set of template-based C++ classes by Microsoft that simplify the programming of Component Object Model (COM) objects.

ATM

Asynchronous Transfer Mode: A cell relay, Circuit switching network and data link layer protocol which encodes data traffic into small fixed-sized cells.

AuthIP

Authenticated Internet Protocol: A Microsoft proprietary extension of the IKE cryptographic protocol which adds a second authentication to the standard IKE authentication which increases security and deployability of IPsec VPNs.

AxIS

ActiveX Installer Service: The ActiveX Installer Service allows users to load ActiveX controls on systems without admin privileges. It is intended for use by business and enterprise (it’s only available in the Business, Enterprise and Ultimate additions of Windows Vista) that would like machines locked down, but still have services that use ActiveX controls.
