Mbps. It is downward-compatible with 802.11a, 802.11b, and 802.11g.
8-bit high color - ANSWER-Describes the VGA mode color setting that, although it can
produce around 16 million different colors, can only display up to 256 different colors at
a time.
AC adapter - ANSWER-A type of power supply that converts AC power to voltages
needed for a device. AC adapters are generally used for portable PC systems and other
devices.
,accelerated graphics port - ANSWER-A local bus designed for video only, it provides a
direct link between the processor and the video card, giving the video card direct
access to main memory.
access control - ANSWER-Managing access to resources. _______ to computers and
network resources involves authentication and authorization.
access control entry - ANSWER-In an access control list, a record containing just one
user or group account name and the permissions assigned to that account.
access control list - ANSWER-A table on each file and folder in the NTFS file system
that contains one or more access control entries.
accessory bay - ANSWER-In a laptop, a compartment that holds a single media device
that is switchable with another.
ACT - ANSWER-The "activity" status light on a NIC that indicates data is being
transmitted.
activation - ANSWER-A method used by several software manufacturers to combat
software piracy.
active communication - ANSWER-A set of behaviors including active listening and
active speaking that shows you are fully engaged in the conversation and encourages
the other person to also communicate in a positive manner.
active listening - ANSWER-A set of skills, behaviors, and attitudes to use when
listening to another person.
active matrix display - ANSWER-An LCD technology based on thin-film transistor (TFT)
technology. It has a transistor at every pixel, which enables much quicker display
changes
,active partition - ANSWER-A primary partition that is marked for use by the system
during startup. Windows operating systems can only be booted from this
active speaking - ANSWER-The appropriate responses that you make during a
conversation.
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.
