Networking Acronyms Flashcards
AAAA
Authentication, Authorisation, Accounting, Auditing
A framework used to control and track access within a computer network.
ACL
Access Control List
A list of permissions associated with a system resource.
AES
Advanced Encryption Standard
A specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology in 2001.
AH
Authentication Header
A deprecated IPsec security protocol that provides integrity protection (but not confidentiality) for packet headers and data.
AP
Access Point
Allows for wireless devices to connect to a wired network.
APC
Angled Physical Contact
A type of fiber connector that minimizes backreflection due to a 5° to 15° angle-polish applied to end faces.
APIPA
Automatic Private Internet Protocol Addressing
Allows devices to automatically assign IP addresses to themselves when they cannot get an IP address from a DHCP server.
ARP
Address Resolution Protocol
Used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address.
AUP
Acceptable Use Policy
Set of rules applied by the owner, creator or administrator of a computer network, website, or service that restricts the ways in which the network, website or system may be used and sets guidelines as to how it should be used.
BGP
Border Gateway Protocol
Determines route based on paths, network policies, or configured rule-set.
BNC
British Naval Connector/ Bayonet Neill-Concelman
A miniature quick connect/disconnect radio frequency connector used for coaxial cable.
CAM
Content Addressable Memory (table)
Special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory or associative storage and compares input search data against a table of stored data, and returns the address of matching data.
CAN
Campus Area Network
Network that spans a limited geographical area. Done so within an educational or corporate environment.
CDMA
Code Division Multiple Access
A form of cellular standards/service. Everyone communicates at the same time. Each call uses a different code. The codes are used to filter each call on the receiving side.
CIA
Confidentiality, Integrity, Availability
Forms the CIA Triad which is the basis for the development of security and encryption systems.
CIDR
Classless Inter-Domain Routing
A method for allocating IP addresses and for IP routing.
CLI
Command-Line Interface
A text-based interface where you can input commands that interact with a computer’s operating system.
CNAME
Canonical Name
A type of DNS record that maps an alias name to a true or canonical domain name (i.e www.example.com and example.com yield same result).
CRC
Cyclical Redundancy Check
An error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data.
CSMA/CA
Carrier-Sense Multiple Access with Collision Avoidance
A network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be “idle”. Effective BEFORE a collision and utilised in most/all WIFI communication.
CSMA/CD
Carrier-Sense Multiple Access with Collision Detection
A medium access control method used most notably in early Ethernet technology for local area networking. It uses carrier-sensing to defer transmissions until no other stations are transmitting. More used for standard ethernet/cabled communication.
CSU
Channel Service Unit
A hardware device that converts a digital data frame from the communications technology used on a local area network (LAN) into a frame appropriate to a wide-area network (WAN) and vice versa.
CVE
Common Vulnerabilities and Exposures
