10Base2
Classification that specifies the use of RG-58 cable and a data rate of 10 Mbps. (2)
10Base5
First IEEE 802.3 classification developed for Ethernet. (2)
10BaseT
Classification specifies the use of the diff erent categories of UTP cable. (2)
6to4
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
Designed to test a person's knowledge related to PC support and repair; pronounced A-
plus. (20)
AAA proxy
Network device that acts as an intermediary to exchange secu-rity packets between the
AAA server and the AAA client. (15)
absorption
Occurs when intervening material absorbs some of the signal. (3)
access method
Method of gaining ac-cess to the network media. (6)

,access port
Hub connection to which each network cable is connected. (1)
acoustical echo
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)
Extension to the original ACPI standard. (9)
Active Directory (AD)
Windows Server standard used to manage large and small network systems. (7)
active hub
Enhanced passive hub; also called an intelligent hub or switch. (1)
active partition
Describes the partition that contains the operating system files the computer should
use to boot. (17)
adaptive cut-through
Frame-forwarding technique that operates as cut-through until an unaccept-able
number of corrupt frames are detected. (11)
Address Resolution Protocol (ARP)
Communication protocol that resolves an assigned IPv4 network address to a physical
address (MAC address). (6)
Address Resolution Protocol (ARP)
Used to map the host MAC address to the logical host IP address. (10)
ad hoc mode
Wireless network arrangement in which a wireless access point is not present. (4)
administrative server
Administers network security and activities. (1)
alien crosstalk (AXT)
Measurement of noise introduced outside the cable jacket, typically caused by other
net-work cables in close proximity. (2)

,American National Standards Institute (ANSI)
Private, nonprofit organization that does not develop standards, but rather prompts
voluntary conformity and standardization. (1)
American Standard Code for Information Interchange (ASCII)
Early attempt to standard-ize data codes. (5)
amplifier
Electronic device designed to raise a signal's amplitude. (2)
analog signal
Signal that has a contin-uous range of values, much like a wave. (2)
analog-to-digital converter (ADC)
Computer chip designed to change an analog signal to a digital signal. (12)
anonymous FTP site
Allows anyone to access the site and download or upload files. (13)
ANT+
Function that can be added to base ANT protocols that allows for interoperability;
pronounced ant plus. (4)
anycast address
IPv6 address that delivers packets to the nearest in-terface; mainly used for supporting
router functions. (10)
application gateway
Provides security for specific applications such as FTP and Telnet. (15)
application layer
Interfaces directly to and performs common application services for the application
process-es; layer seven of the OSI model. (1)
archive bit
Identifies if a file has changed since the last full or incremental backup. (16)
asymmetric-key encryption
Encryption method that uses two keys: a private key and a public key; also known as
public-key cryptography. (15)
3|Page
, 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
