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
CWDM
Coarse Wavelength Division Multiplexing
- allows data streams to be sent simultaneously over a single optical fiber network. For shorter distances (than DWDM)
