ad hoc mode - (ANSWER)In a Wi-Fi network, the networking mode that allows peer-to-peer
communications without the use of a centralized wireless hub, called a wireless access point (WAP).
adapter card - (ANSWER)A printed circuit card that you add to the motherboard to enhance
functionality. Also called an expansion card. Video adapters and network interface cards (NICs) are
examples of this
address bus - (ANSWER)A group of wires used to identify addresses in main system memory in a
computer. The number of wires in an address bus is called the width of the bus and determines the
number of unique memory locations that can be addressed using binary math with the two raised to the
power of the number of wires in the bus. A 32-bit bus can address up to 4 GB of memory, whereas a 36-
bit address bus can address up to 64 GB of memory.
Address Resolution Protocol - (ANSWER)A protocol used to resolve an IP address to a MAC address.
Advanced Communications Riser - (ANSWER)A riser card standard that AMD, 3Com, and others
introduced in 2000 to supersede AMR. It uses one PCI slot, provides accelerated audio and modem
functions as well as networking, and supports multiple Ethernet NICs.
Advanced Configuration and Power Interface - (ANSWER)A power management standard that includes
all the power states of APM, plus two more. It also supports soft power.
Advanced Micro Devices - (ANSWER)AMD manufactures CPUs and other products, and its chief rival is
Intel Corporation.
Advanced Power Management - (ANSWER)A power management standard, introduced by Intel in 1992,
that defines four power-usage operating levels.
Advanced Technology - (ANSWER)A type of motherboard used in older PC systems; also refers to the
1984 IBM PC AT model.

Advanced Technology Attachment - (ANSWER)The former name of the Parallel AT Attachment (PATA)
interface standard.
Advanced Technology eXtended - (ANSWER)A type of motherboard and its variants most commonly used
in recent PC systems.
adware - (ANSWER)Software installed on a computer without permission that collects information about
a user in order to display targeted advertisements, in the form of either inline banners or pop-ups. Inline
banners are advertisements that run within the context of the current page, taking up screen real estate.
alternating current - (ANSWER)The delivery of electricity (as from a wall outlet) in which the flow of
electrons reverses periodically and has alternating positive and negative values.
amperes (amps) - (ANSWER)A measurement of the volume of electrons, also called current. It is
calculated with the formula amps = watts / volts.
analog LCD display - (ANSWER)An LCD display that uses a DB-15 connector, which means that it accepts
analog signals that it converts to digital.
analog modem - (ANSWER)A modulator/demodulator device that allows computers to communicate
with one another over existing phone lines.
answer file - (ANSWER)A file used during an unattended installation of Windows. It provides a script of
responses to the questions Setup asks so the user does not have to answer them manually.
antistatic mat - (ANSWER)A mat that provides a path to ground for a static charge and is designed for the
desktop or floor of a workspace. One placed on the workbench reduces the risk of electrostatic
discharge for components placed on it, while one placed on the floor provides the same protection for
anyone standing on the mat.
