Mta 98-366 Networking Fundamentals - Acronyms

ARP is used to map an IP address to a MAC address, allowing devices to communicate on a local network.

ADSL stands for Asymmetrical Digital Subscriber Lines which allows customers to be on the Internet and receive phone calls simultaneously while having faster download speeds compared to upload speeds.

AES stands for Advanced Encryption Standard, which is a symmetric block cipher known for its strong encryption capabilities. It is commonly used in wireless networks with WPA2 for secure communication.

In networking and security, AH stands for Authentication Header, which is a protocol used to provide connectionless integrity and data origin authentication for IP datagrams and to protect against replay attacks. AH is one of the two IPsec protocols, with the other being ESP (Encapsulating Security Payload).

NAT stands for Network Address Translation, which is a process used in computer networking to modify network address information in the IP header of packets while they are in transit.

DHCP stands for Dynamic Host Configuration Protocol and is used to automatically assign IP addresses and other network configuration settings to devices on a network.

NAP stands for Network Access Protection, a Microsoft technology for controlling network access of computers based on policy compliance.

DDNS stands for Dynamic Domain Name System, which is a method of automatically updating a domain name in real time by linking it to a changing IP address. It is commonly used in situations where a fixed IP address is not available or practical.

The Domain Name System (DNS) is a system used for translating domain names to IP addresses on the internet. It is responsible for mapping human-friendly domain names to the numeric IP addresses required for locating and identifying computer services and devices with the underlying network protocols.

SMTP stands for Simple Mail Transfer Protocol and is used for sending or relaying email from a server. It operates on Port 25 TCP for communication.

LAN stands for Local Area Network, which is a network that connects computers and devices in a limited geographical area such as a home, school, or office building.

DMZ commonly refers to a Demilitarized Zone, which is a buffer area between two countries where military activities are restricted or prohibited.

CSMA/CD is a protocol used in wired networks, specifically in the 802.3 Ethernet standard. It helps to manage access to the network and detect collisions when multiple devices try to communicate at the same time.

CSMA/CA specifically deals with the 802.11 wireless network access by using carrier sense to listen before transmitting and collision avoidance to prevent data collisions.

NOS stands for Network Operating System, which is the operating system commonly found on routers and switches.

VLAN stands for Virtual Local Area Network, which is a technology that allows for the segmentation of networks without actually physically separating the devices.

WLAN refers to a type of network that allows devices to connect and communicate wirelessly within a limited area, typically within a home, office, or public hotspot.

P2P refers to a decentralized communications model in which each party has the same capabilities and either party can initiate a communication session.

PC commonly refers to Personal Computer, which is a general-purpose computer for individual use.

MAC in the context of networking typically refers to Media Access Control, which is used to uniquely identify network devices.

DSL stands for Digital Subscriber Line, which is a type of high-speed internet connection that uses existing telephone lines to transmit data.

NIC stands for Network Interface Card, which is a hardware component that allows computers to connect to a network.

SOHO typically refers to small businesses or individuals who work from a home office setting.

USB stands for Universal Serial Bus, which is a common interface used for connecting devices such as printers, cameras, keyboards, and external drives to a computer.

The CPU, or Central Processing Unit, is the primary component of a computer that performs most of the processing inside a computer.

ROM stands for Read-Only Memory, which is a type of non-volatile memory used in computers and other electronic devices to permanently store data that cannot be changed or modified.

PCI stands for Peripheral Component Interconnect, which is a local computer bus for attaching hardware devices in a computer.

Mbps stands for Megabits per second, not MegaBytes, Microbits, or MegaPixels.

Gbps stands for Gigabits per second, which is a unit of data transfer rate equal to 1,000,000,000 bits per second.
