Many researchers have recognized these kinds of supply network structures as a new organization form, using terms such as " Keiretsu ", " Extended Enterprise ", " Virtual Corporation ", " Global Production Network ", and " Next Generation Manufacturing System ".

The Semi-Automatic Ground Environment ( SAGE ) was the Cold War operator environment created for the automated air defense ( AD ) of North American and by extension, the name of the associated network of radars, computer systems, and aircraft command and control equipment (" SAGE Defense System ") to replace the United States Air Force " manual air defense system " ( Col John Morton ).

That's the UNL Society, a global-scale network of R & D teams, involving about 200 specialists in computer science and linguistics, who are at work creating the linguistic resources and developing the web structure of the UNL System.

* Global System for Mobile Communications ( GSM ): The GSM network is divided into three major systems: the switching system, the base station system, and the operation and support system.

The X window system ( commonly X Window System or X11, based on its current major version being 11 ) is a computer software system and network protocol that provides a basis for graphical user interfaces ( GUIs ) and rich input device capability for networked computers.

The network has its origins in United Independent Broadcasters Inc., a collection of 16 radio stations that was bought by William S. Paley in 1928 and renamed the Columbia Broadcasting System.

The fledgling network soon needed additional investors though, and the Columbia Phonograph Company, manufacturers of Columbia Records, rescued it in April 1927 ; as a result, the network was renamed " Columbia Phonographic Broadcasting System.

During the first decade of the Internet after the invention of the Domain Name System ( DNS ) it became apparent that the devised system based on the classful network scheme of allocating the IP address space and the routing of IP packets was not scalable.

It is proposed that in 10 years all commercial timberlands, all critical watersheds, and other lands in the National Forest System developed or proposed for intensive use will be given protection from fire adequate to meet the fire situation in the worst years and under serious peak loads.

In general, the International System of Units only uses capital letters for the symbols of units which are named after individual scientists, while au or a. u.

" As such, the meter is undefined for the purposes of measuring distances within the Solar System.

While over the far side of the Moon, the Command / Service Module's Service Propulsion System engine burned for six minutes and fifteen seconds, braking the spacecraft into an orbit around the Moon with a low point ( pericynthion ) of 58. 3 and a high point ( apocynthion ) of 170. 4 nautical miles ( 108. 0 and 315. 6 km, respectively ).

Originally released for the IBM 6150 RISC workstation, AIX now supports or has supported a wide variety of hardware platforms, including the IBM RS / 6000 series and later IBM POWER and PowerPC-based systems, IBM System i, System / 370 mainframes, PS / 2 personal computers, and the Apple Network Server.

AIX Version 1, introduced in 1986 for the IBM 6150 RT workstation, was based on UNIX System V Releases 1 and 2.

Among other variants, IBM later produced AIX Version 3 ( also known as AIX / 6000 ), based on System V Release 3, for their IBM POWER-based RS / 6000 platform.

Since 1990, AIX has served as the primary operating system for the RS / 6000 series ( later renamed IBM eServer pSeries, then IBM System p, and now IBM Power Systems ).

In 2003, the SCO Group alleged that ( among other infractions ) IBM had misappropriated licensed source code from UNIX System V Release 4 for incorporation into AIX ; SCO subsequently withdrew IBM's license to develop and distribute AIX.

The original AIX ( sometimes called AIX / RT ) was developed for the IBM 6150 RT workstation by IBM in conjunction with Interactive Systems Corporation, who had previously ported UNIX System III to the IBM PC for IBM as PC / IX.

AIX / 370 was IBM's third attempt to offer Unix-like functionality for their mainframe line, specifically the System / 370 ( the prior versions were a TSS / 370 based Unix system developed jointly with AT & T c. 1980, and VM / IX a VM / 370 based system developed jointly with Interactive Systems Corporation c. 1984 ).
