A Record - CORRECT ANSWER>>>>DNS record of the IPv4 address
of a domain or host.
AAAA Record - CORRECT ANSWER>>>>DNS record of the IPv6
address of a domain or host.
Access Control List (ACL) - CORRECT ANSWER>>>>A security
scheme for network-level security.
Access Point - CORRECT ANSWER>>>>A wireless radio that
transmits and receives Wi-Fi signals.
Acronym - CORRECT ANSWER>>>>An abbreviation formed by the
first letters of other words.
Address - CORRECT ANSWER>>>>A number identifying a location
on the internet or other network.
Alias Record - CORRECT ANSWER>>>>DNS record that enables
hosts to have more than one name.
Application Layer - CORRECT ANSWER>>>>The layer where users
communicate with the network stack through application program
interfaces, or APIs, that connect the application in use with the operating
system of the computer.
1
,Application Programming Interface (API) - CORRECT
ANSWER>>>>The computer code in an application that calls for
remote networked services.
Application Server - CORRECT ANSWER>>>>A server that makes
applications remotely available to network users; application servers
often also integrate with databases connected to the applications.
Application-Specific Integrated Circuit (ASIC) - CORRECT
ANSWER>>>>An integrated circuit (IC) chip designed for a particular
use.
Attachment Unit Interface (AUI) - CORRECT ANSWER>>>>A
physical and logical interface defined in the original IEEE 802.3
standard for 10BASE5 Ethernet and the previous DIX standard.
Attenuation - CORRECT ANSWER>>>>Signal loss over distance.
Azure - CORRECT ANSWER>>>>A Microsoft cloud-based platform
for deploying network services including virtual desktops.
Back off - CORRECT ANSWER>>>>To defer transmission.
Bandwidth - CORRECT ANSWER>>>>The rate of data flow in digital
networks typically measured in bits per second; the bit rate.
Baud Rate - CORRECT ANSWER>>>>The number of signaling events
per second.
Best-Effort Service - CORRECT ANSWER>>>>A network
transmission via a connectionless protocol that does not guarantee
delivery.
2
, Binary - CORRECT ANSWER>>>>Being in one of two mutually
exclusive states, such as on or off. Binary states are often represented as
1 and 0 in computer science.
Binary Code - CORRECT ANSWER>>>>A code that uses the binary
digits 0 and 1, usually in groups of eight, to represent characters,
machine instructions, or other data.
Bit - CORRECT ANSWER>>>>The smallest unit of storage in a digital
computer, consisting of a binary digit.
Bit Rate - CORRECT ANSWER>>>>The frequency at which bits
(binary digits) pass a given physical or metaphorical point, measured in
bps (bits per second).
Bluetooth - CORRECT ANSWER>>>>Wireless protocol used in
personal area networks.
Bps - CORRECT ANSWER>>>>Bytes per second.
Bridge - CORRECT ANSWER>>>>A two-port Layer 2 device that
forwards frames based on MAC addresses.
Broadcast - CORRECT ANSWER>>>>A transmission addressed to all
stations.
Broadcast Domain - CORRECT ANSWER>>>>The area of a network
where a broadcast will be received by all stations.
Burned-In-Address (BIA) - CORRECT ANSWER>>>>The MAC
address permanently assigned to a network interface card.
Bus Topology - CORRECT ANSWER>>>>All computers are
connected to a single straight cable installed in a workspace.
