Telecomm and Wireless Communications - D413 WGU
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)
,Telecomm and Wireless Communications - D413 WGU
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)
,Telecomm and Wireless Communications - D413 WGU
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)
, Telecomm and Wireless Communications - D413 WGU
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)
