Integrated Services Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the digitalised circuits of the public switched telephone network. [1] Work on the standard began in 1980 at Bell Labs and was formally standardized in 1988 in the CCITT "Red ...
A computer network is a set of computers sharing resources located on or provided by network nodes.Computers use common communication protocols over digital interconnections to communicate with each other.
It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.
Before B-ISDN, the original ISDN attempted to substitute the analog telephone system with a digital system which was appropriate for both voice and non-voice traffic. . Obtaining worldwide agreement on the basic rate interface standard was expected to lead to a large user demand for ISDN equipment, hence leading to mass production and inexpensive ISDN
The Integrated Services Digital Network is an evolution of the Public Switched Telephone Network that builds upon the latter's digitisation in order to offer enriched functionality. For more information, see Integrated Services Digital Network .
The Broadband Integrated Services Digital Network (B-ISDN) was designed for these needs. [13] The types of traffic supported by a broadband network can be classified according to three characteristics: [14] Bandwidth is the amount of network capacity required to support a connection. Latency is the amount of delay associated with a connection.
Digital communication to the end user using Integrated Services Digital Network (ISDN) services became available in the late 1980s. Since the end of the 1990s, broadband access techniques such as ADSL , Cable modems , fiber-to-the-building (FTTB) and fiber-to-the-home (FTTH) have become widespread to small offices and homes.
Digital Living Network Alliance (DLNA) is a set of interoperability standards for sharing home digital media among multimedia devices. It allows users to share or stream stored media files to various certified devices on the same network like PCs, smartphones, TV sets, game consoles, stereo systems, and NASs. [1]
