Dynamic spectrum access (DSA), also referred to as dynamic spectrum management (DSM), is a set of spectrum utilization techniques that adjusts frequency in real time based on fluctuating circumstances.

Wireline communication (also known as wired communication) is the transmission of information over a physical filament. Alternatively, communication technologies that transmit information over-the-air (OTA) are called wireless.

Interconnection is a strategy for ensuring that businesses can privately, securely and directly exchange digital information. An important goal of interconnection is to enable extremely high bandwidth exchanges with the lowest possible latency, at the lowest cost.

An intrusion prevention system (IPS) is a network security and threat prevention tool.

A keylogger, sometimes called a keystroke logger or system monitor, is a type of surveillance technology used to monitor and record each keystroke typed on a specific computer's keyboard.

WAN optimization -- also known as WAN acceleration -- is the category of technologies and techniques used to maximize the efficiency of data's flow across a wide area network (WAN), between organizations' centralized data centers and their remote locations.

Remote Procedure Call (RPC) is a protocol that one program can use to request a service from a program located in another computer on a network without having to understand the network's details.

A subnet, or subnetwork, is a segmented piece of a larger network.

Remote access is the ability for an authorized person to access a computer or a network from a geographical distance through a network connection. Remote access enables users to connect to the systems they need when they are physically far away. This is especially important for employees who work at branch offices, are traveling or telecommute to work.

TCP (Transmission Control Protocol) is a standard that defines how to establish and maintain a network conversation through which application programs can exchange data.

Remote access is the ability for an authorized person to access a computer or a network from a geographical distance through a network connection. Remote access enables users to connect to the systems they need when they are physically far away. This is especially important for employees who work at branch offices, are traveling or telecommute to work.

Microsoft Azure, formerly known as Windows Azure, is Microsoft's public cloud computing platform.

CIDR (Classless Inter-Domain Routing) -- also known as supernetting -- is a method of assigning Internet Protocol (IP) addresses that improves the efficiency of address distribution and replaces the previous system based on class A, class B and class C networks.

A Martian address is a source or destination IP address that apparently does not exist on Planet Earth and is, thus, invalid and/or non-routable.

An edge router is a specialized router located at a network boundary that enables an internal network to connect to external networks.

The Advanced Encryption Standard (AES) is a symmetric block cipher chosen by the U.S. government to protect classified information.

The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

Network bandwidth is the capacity of a wired or wireless network communications link to transmit the maximum amount of data from one point to another over a computer network or internet connection in a given amount of time -- usually, one second.

An SSL VPN is a type of virtual private network (VPN) that uses the Secure Sockets Layer (SSL) protocol -- or, more often, its successor, the Transport Layer Security (TLS) protocol -- in standard web browsers to provide secure, remote-access VPN capability.

Android OS is a Linux-based mobile operating system that primarily runs on smartphones and tablets.

Ethernet is the traditional technology for connecting devices in a wired local area network (LAN) or wide area network (WAN), enabling them to communicate with each other via a protocol -- a set of rules or common network language.

A static IP address is a 32 bit number that is assigned to a computer to be its address on the internet.

Cloud telephony, also known as cloud calling, is a type of unified communications as a service (UCaaS) that offers voice communication services through a third-party host.

Unified communications (UC) is a framework for integrating various asynchronous and real-time communication tools.

A virtual private network (VPN) is programming that creates a safe, encrypted connection over a less secure network, such as the public internet. A VPN uses tunneling protocols to encrypt data at the sending end and decrypt it at the receiving end.

A Wi-Fi Pineapple is a wireless auditing platform from Hak5 that allows network security administrators to conduct penetration tests.

Network bandwidth is the capacity of a wired or wireless network communications link to transmit the maximum amount of data from one point to another over a computer network or internet connection in a given amount of time -- usually, one second.
