The Session Initiation Protocol (SIP) is a communications protocol for signaling, for the purpose of controlling multimedia communication sessions.

Internet telephony, business IP telephone systems, service providers and carriers use SIP.

SIP can be used to set up and control voice and video calls, as well as instant messaging.

The most common application of SIP is the setup and termination of Voice over IP (VoIP) telephone calls.

Voice over Internet Protocol (Voice over IP, VoIP and IP telephony) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.

The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).

Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand.

It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., computer networks, servers, storage, applications and services), which can be rapidly provisioned and released with minimal management effort.

Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in either privately owned, or third-party data centers that may be located far from the user–ranging in distance from across a city to across the world.

Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to a utility (like the electricity grid) over an electricity network.

A computer network or data network is a telecommunications network which allows nodes to share resources.

In computer networks, networked computing devices exchange data with each other using a data link.

The connections between nodes are established using either cable media or wireless media.

The best-known computer network is the Internet.

Telecommunication is the transmission of signs, signals, messages, writings, images and sounds or intelligence of any nature by wire, radio, optical or other electromagnetic systems.

Telecommunication occurs when the exchange of information between communication participants includes the use of technology.

It is transmitted either electrically over physical media, such as cables, or via electromagnetic radiation.

Such transmission paths are often divided into communication channels which afford the advantages of multiplexing.

The term is often used in its plural form, telecommunications, because it involves many different technologies.
