And Definitions!- Exam Study Guide with
Verified Answers | Guaranteed Success
AC
Alternating Current: an electric current that reverses its direction many times a second at
regular intervals, typically used in power supplies.
ACL
access control lists.
An ACL is a list attached to a resource, giving permissions, or rules about exactly who can access
it.
ACPI
Advanced Configuration Power Interface: provides an open standard that operating systems
can use to discover and configure computer hardware components, to perform power
management by (for example) putting unused components to sleep, and to perform status
monitoring.
ADF
automatic document feeder (ADF) is a feature in printers, photocopiers, fax machines or
scanners wherein a stack of paper put into the machine and is then automatically fed through
it, allowing the user to print, scan or copy without having to manually place each page into the
machine
ADSL
Asymmetric Digital Subscriber Line: ADSL is a technology that will oterm-5ffer faster connection
speeds than the traditional Internet via dial-up telephone lines could offer. ADSL is the
technology that drives many Internet connections worldwide.
AES
,Advanced Encryption Standard: is a specification for the encryption of electronic data
established by the U.S. National Institute of Standards and Technology (NIST) in 2001.
AHCI
The Advanced Host Controller Interface (AHCI) is a technical standard defined by Intel that
specifies the operation of Serial ATA (SATA) host controllers in a non-implementation-specific
manner in its motherboard chipsets.
AP
In computer networking, a wireless access point (WAP), or more generally just access
point (AP), is a networking hardware device that allows other Wi-Fi devices to connect to a
wired network.
APIPA
APIPA stands for Automatic Private IP Addressing (APIPA). It is a feature or characteristic in
operating systems (eg. Windows) which enables computers to self-configure an IP address and
subnet mask automatically when their DHCP(Dynamic Host Configuration Protocol) server isn't
reachable.
APM
Advanced Power Management (APM) is an application programming interface (API) developed
jointly by Microsoft and Intel. It allows an operating system to communicate with the
computer's BIOS in order to achieve efficient power management.
ARP
ARP stands for Address Resolution Protocol. When you try to ping an IP address on your local
network, say 192.168. ... If there is a value cached, ARP is not used. If the IP address is not
found in the ARP table, the system will then send a broadcast packet to the network using
the ARP protocol to ask "who has 192.168.
ASR
Automated system recovery (ASR) is a feature of the Windows XP operating system that can be
used to simplify recovery of a computer's system or boot volumes. ASR consists of two parts:
an automated backup, and an automated restore. The backup portion can be accessed in the
Backup utility under System Tools.
ATA
, Stands for "Advanced Technology Attachment." It is a type of disk drive that integrates the
drive controller directly on the drive itself. Computers can use ATA hard drives without a specific
controller to support the drive.
ATAPI
Advanced Technology Attachment Packet Interface (ATAPI) is a protocol that allows a greater
variety of devices to be connected to a computer than ATA (PATA / IDE and SATA) on its own
would allow. ATAPI allows IDE and SATA controllers to support optical drives.
ATM
Asynchronous Transfer Mode (ATM) is a telecommunications standard defined by ANSI and ITU
(formerly CCITT) for digital transmission of multiple types of traffic, including telephony (voice),
data, and video signals in one network without the use of separate overlay networks.
ATX
Short for Advanced Technology eXtended, ATX is a specification used to outline motherboard
configuration and dimensions to improve standardization.
AUP
An acceptable use policy (AUP) is a document stipulating constraints and practices that
a user must agree to for access to a corporate network or the Internet.
A/V
(Audio/Video) Equipment and applications that deal with sound and sight. The A/V world
includes microphones, tape and disk recorders, audio mixers, still and video cameras, film
projectors, data projectors, slide projectors, VCRs, CD/DVD/Blu-ray players/recorders, amplifiers
and speakers.
BD-R
Blu-ray Disc Recordable (BD-R) refers to two direct to disc optical disc recording technologies
that can be recorded on to a Blu-ray-based optical disc with an optical disc recorder.
BIOS
BIOS (basic input/output system) is the program a computer's microprocessor uses to start the
computer system after it is powered on. It also manages data flow between the computer's
operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard,
mouse and printer.
