Omegle is a free online chat website that allows users to socialize with others without the need to register.

The service randomly pairs users in one-on-one chat sessions where they chat anonymously using the names "You" and "Stranger" or "Stranger 1" and "Stranger 2" in the case of Spy mode.

The site was created by 18-year-old Leif K-Brooks of Brattleboro, Vermont, and was launched on March 25, 2009.

Less than a month after launch, Omegle garnered around 150,000 page views a day, and in March 2009 the site introduced a video conferencing feature.

The site now provides a mobile application that lets users chat with strangers from mobile devices.

Videotelephony comprises the technologies for the reception and transmission of audio-video signals by users at different locations, for communication between people in real-time.

A videophone is a telephone with a video display, capable of simultaneous video and audio for communication between people in real-time.

Videoconferencing implies the use of this technology for a group or organizational meeting rather than for individuals, in a videoconference.

Telepresence may refer either to a high-quality videotelephony system (where the goal is to create the illusion that remote participants are in the same room) or to meetup technology, which goes beyond video into robotics (such as moving around the room or physically manipulating objects).

Videoconferencing has also been called "visual collaboration" and is a type of groupware.

Information is any entity or form that provides the answer to a question of some kind or resolves uncertainty.

It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts.

As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.

File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia (audio, images and video), documents or electronic books.

File sharing may be achieved in a number of ways.

Common methods of storage, transmission and dispersion include manual sharing utilizing removable media, centralized servers on computer networks, World Wide Web-based hyperlinked documents, and the use of distributed peer-to-peer networking.

In publishing, art, and communication, content is the information and experiences that are directed towards an end-user or audience.

Content is "something that is to be expressed through some medium, as speech, writing or any of various arts".

Content can be delivered via many different media including the Internet, cinema, television, smartphones, audio CDs, books, e-books, magazines, and live events, such as speech, conferences and stage performances.
