Fog computing is a decentralized computing infrastructure in which data, compute, storage and applications are located somewhere between the data source and the cloud.

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.

Data center services is a collective term for all the supporting components necessary to the proper operation of data center. This includes all the implementation, maintenance and operation of a data center.

Infrastructure is the foundation or framework that supports a system or organization.

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

Quality of service (QoS) refers to any technology that manages data traffic to reduce packet loss, latency and jitter on the network.

Software-defined networking (SDN) is an architecture that abstracts different, distinguishable layers of a network in order to make networks agile and flexible.

A virtual private network (VPN) is a service that creates a safe, encrypted online connection.

PaaS (platform as a service) is a cloud computing model where a third-party provider delivers hardware and software tools to users over the internet.

Cloud computing is a general term for anything that involves delivering hosted services over the internet.

VoIP (voice over Internet Protocol) is the transmission of voice and multimedia content over an internet connection.

Telecommunications, also known as telecom, is the exchange of information over significant distances by electronic means and refers to all types of voice, data and video transmission.

Generally, a configuration is the arrangement - or the process of making the arrangement - of the parts that make up a whole.
