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).

HTTPS (also called HTTP over TLS, HTTP over SSL, and HTTP Secure) is a protocol for secure communication over a computer network which is widely used on the Internet.

HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security, or its predecessor, Secure Sockets Layer.

The main motivation for HTTPS is authentication of the visited website and protection of the privacy and integrity of the exchanged data.

Fax (short for facsimile), sometimes called telecopying or telefax (the latter short for telefacsimile), is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output device.

The original document is scanned with a fax machine (or a telecopier), which processes the contents (text or images) as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones.

The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy.

Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner.

Since the 1980s, most machines modulate the transmitted audio frequencies using a digital representation of the page which is compressed to quickly transmit areas which are all-white or all-black.

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.

In computing, a virtual machine (VM) is an emulation of a computer system.

Virtual machines are based on computer architectures and provide functionality of a physical computer.

Their implementations may involve specialized hardware, software, or a combination.
