Success!!
asymmetric-key encryption
Encryption method that uses two keys: a private key and a public
key; also known as public-key cryptography. (15)
asynchronous transfer mode (ATM)
Protocol designed especially for transmitting data, voice, and video.
(1)
asynchronous transmission
Data transmission method in which no reference signal is present. (5)
,attenuation
Loss of signal strength. (1)
auditing
Service that tracks the events, use, and access of network resources
and writes these actions to a log. (7)
authentication
Process used to identify a user and ensure the user is who he or she
claims to be; also known as local authentication. (15)
authentication, authorization, and accounting (AAA)
Security standard that consists of three parts: authentication,
authorization, and accounting; also known as triple A. (15)
Automatic Configuration and Power Interface (ACPI)
Standard for controlling the power options for computer hardware
devices. (9)
,automatic medium-dependent interface crossover (Auto-MDIX)
Electronic chip technology incorpo-rated into Gigabit Ethernet
devices to automatically reassign pin func-tions and eliminate the
need for a crossover cable. (2)
Automatic Private IP Addressing (APIPA)
Feature that assigns an IP address from a special set of IP ad-
dresses that have been set aside by IANA when a DHCP server
cannot be reached. (10)
available bit rate (ABR)
ATM data transfer classification most appro-priate for file transfer
because it uses the available bit rate associated with the networking
medium. (12)
average utilization
Measurement of the average amount of utilization or traffic on a
network in a given monitoring period. (16)
AWG rating
Describes the size of a conductor's diameter. (2)
backbone
Connects the telecommuni-cation closets, equipment rooms, and
main entrance facility. (18)
, backdoor
Software access port to a computer infected by a Trojan horse
backplane
Simple motherboard designed with minimal components. (9)
bandwidth
Measurement of the network media's ability to carry data. (2)
Bandwidth Allocation Protocol (BAP)
Allows the number of lines used by MLPPP to change on demand.
(14)
bandwidth shaper
Used to prioritize network packets to ensure quality of service for
time-sensitive applica-tions such as VoIP; also known as a traffic
shaper. (12)
baseband
Method of transmitting data in the form of a digital signal, using the
entire bandwidth of a cable. (2)
