Answer: Mechanism that provides a means of communicating across the
IPv4 Internet while preserving the orig-inal IPv6 assigned address of the
network device. (10)
●● A+ Certification
Answer: Designed to test a person's knowledge related to PC support
and repair; pronounced A-plus. (20)
●● AAA proxy
,Answer: Network device that acts as an intermediary to exchange secu-
rity packets between the AAA server and the AAA client. (15)
●● absorption
Answer: Occurs when intervening material absorbs some of the signal.
(3)
●● access method
Answer: Method of gaining ac-cess to the network media. (6)
●● access port
Answer: Hub connection to which each network cable is connected. (1)
●● acoustical echo
Answer: Condition that takes place when a microphone and a speaker
are in close proximity or the audio is improperly adjusted, causing
feedback. (12)
●● ACPI Component Architecture (ACPICA)
Answer: Extension to the original ACPI standard. (9)

Answer: Enhanced passive hub; also called an intelligent hub or switch.
(1)
●● active partition
Answer: Describes the partition that contains the operating system files
the computer should use to boot. (17)
●● adaptive cut-through
Answer: Frame-forwarding technique that operates as cut-through until
an unaccept-able number of corrupt frames are detected. (11)
●● Address Resolution Protocol (ARP)
Answer: Communication protocol that resolves an assigned IPv4
network address to a physical address (MAC address). (6)
●● Address Resolution Protocol (ARP)
Answer: Used to map the host MAC address to the logical host IP
address. (10)
●● ad hoc mode
, Answer: Wireless network arrangement in which a wireless access point
is not present. (4)
●● administrative server
Answer: Administers network security and activities. (1)
●● alien crosstalk (AXT)
Answer: Measurement of noise introduced outside the cable jacket,
typically caused by other net-work cables in close proximity. (2)
●● American National Standards Institute (ANSI)
Answer: Private, nonprofit organization that does not develop standards,
but rather prompts voluntary conformity and standardization. (1)
●● American Standard Code for Information Interchange (ASCII)
Answer: Early attempt to standard-ize data codes. (5)
●● amplifier
Answer: Electronic device designed to raise a signal's amplitude. (2)
●● analog signal
Answer: Signal that has a contin-uous range of values, much like a
wave. (2)
