What is the more virtual repository?
Multiple virtual storage, more often known as MVS, is the mainframe operating system (OS) developed by International Business Machines ™ (IBM) in 1974. The current version of the system of multiple virtual storage system is completely compatible with older OS versions and UNIX ™ operating system.
The history of multiple virtual storage begins with the development of MVT. This OS was supposed to be a selection system for large IBM ™ mainframes. Subsequent delays and problems with the initial release prevented people in full acceptance of the system, and many people followed the current multiprogramming with a fixed number of tasks (MFT) OS.
The release of more virtual storage should be a start that would bring people to a new system. It was released as an update of current IBM ™ operating systems, especially MVT. The differences in programming were so great that it was widely considered a new system. As a result, users that tThe éhořím immediately began to call MVS and IBM ™ soon did.
The abbreviation MVS was included in its own name of each edition of 1978 with MVS/Special Edition (MVS/SE) until 1988 with the architecture of MVS/Enterprise System Architecture (MVS/ESA). In 1995 it released IBM ™ OS/390. Although this system did not include the MVS in its name, it was a direct successor to the system. Since OS/390, the MVS has not been returned to the system update name.
While most versions of multiple virtual repositories were simply the basic improvement of the basic system, MVS/Systems (MVS/SP) Contained support for UNIX ™ systems. Since its release in 1980, the availability of UNIX ™ has created backward compatibility of the IBM ™ for the MVS system. This strengthened the OS as one of the largest used system computers used.
In addition to multiple virtual storage, IBM ™ has several other surgicals on the marketh systems. A number of TPF processing (TPF) works primarily with airlines and other volume processing organizations to maintain organized and secure records. The virtual machine line (VM) emulates Mainframe operations on computers without mainframe, the most famous version is Hercules. Finally, IBM maintains several expansion of the UNIX ™ and UNIX ™ operating system, which allows popular OSS created by other companies to work on their bags as a separate operating system.
