A low Earth orbit (LEO) is an Earth-centered orbit close to the planet, often specified as an orbital period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of the Earth.

The term "LEO region" is also used for the area of space below an altitude of 2,000 km (1,200 mi) (approximately one-third of the radius of Earth). Objects in orbits which pass through this area, even if they have an apogee further out, or are sub-orbital, are carefully tracked because they present a collision risk to the many satellites in LEO.

All crewed space stations to date have been in LEO. From 1968 to 1972 the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, there have been no human spaceflights beyond LEO.

The ISDN (Integrated Services Digital Network) User Part or ISUP is part of Signaling System No. 7 (SS7), which is used to set up telephone calls in the public switched telephone network (PSTN). It is specified by the ITU-T as part of the Q.76x series.

When a telephone call is set up from one subscriber to another, several telephone exchanges could be involved, possibly across international boundaries. To allow a call to be set up correctly, where ISUP is supported, a switch will signal call-related information like called party number to the next switch in the network using ISUP messages.

The telephone exchanges may be connected via T1 or E1 trunks which transport the speech from the calls. These trunks are divided into 64 kbit/s timeslots, and one timeslot can carry exactly one call. Regardless of what facilities are used to interconnect switches, each circuit between two switches is uniquely identified by a circuit identification code (CIC) that is included in the ISUP messages. The exchange uses this information along with the received signaling information (especially the called party number) to determine which inbound and outbound circuits should be connected together to provide an end to end speech path.

In addition to call related information, ISUP is also used to exchange status information for, and permit management of, the available circuits. In the case of no outbound circuit being available on a particular exchange, a release message is sent back to the preceding switches in the chain.

Interactive television (also known as ITV or iTV) is a form of media convergence, adding data services to traditional television technology. Throughout its history, these have included on-demand delivery of content, as well as new uses such as online shopping, banking, and so forth. Interactive TV is a concrete example of how new information technology can be integrated vertically (into established technologies and commercial structures) rather than laterally (creating new production opportunities outside existing commercial structures, e.g. the world wide web).

The JPEG File Interchange Format (JFIF) is an image file format standard. It defines supplementary specifications for the container format that contains the image data encoded with the JPEG algorithm. The base specifications for a JPEG container format are defined in Annex B of the JPEG standard, known as JPEG Interchange Format (JIF). JFIF builds over JIF to solve some of JIF's limitations, including unnecessary complexity, component sample registration, resolution, aspect ratio, and color space. Because JFIF is a supplementary standard, the resulting file format may be referred to as "JPEG/JFIF".

JFIF is mutually incompatible with the newer Exchangeable image file format (Exif).

The Internet Society (ISOC) is an American nonprofit advocacy organization founded in 1992.
