2. MVS - Wikipedia

   en.wikipedia.org/wiki/MVS

   Multiple Virtual Storage, more commonly called MVS, is the most commonly used operating system on the System/370, System/390 and IBM Z IBM mainframe computers. IBM developed MVS, along with OS/VS1 and SVS, as a successor to OS/360. It is unrelated to IBM's other mainframe operating system lines, e.g., VSE, VM, TPF.

   On May 19, 1992, IBM announced [10] DFSMS/MVS, 5695-DF1, replacing MVS/Data Facility Product (MVS/DFP) Version 3, 5665-XA3, Data Facility Hierarchical Storage Manager (DFHSM) Version 2, 5665-329 and Data Facility Data Set Services (DFDSS) Version 2, 5665-327. DFSMS/MVS also replaced utilities and service aids.

   en.wikipedia.org/wiki/Job_Entry_Subsystem_2/3

   The Job Entry Subsystem (JES) is a component of IBM's MVS mainframe operating systems that is responsible for managing batch workloads. In modern times, there are two distinct implementations of the Job Entry System called JES2 and JES3. They are designed to provide efficient execution of batch jobs.

7. Time Sharing Option - Wikipedia

   en.wikipedia.org/wiki/Time_Sharing_Option

   When it was introduced in 1971, [3] IBM considered time-sharing an "optional feature", as compared to standard batch processing, and hence offered TSO as an option for OS/360 MVT. With the introduction of MVS in 1974, IBM made it a standard component of their top-end mainframe operating system.

8. VM (operating system) - Wikipedia

   en.wikipedia.org/wiki/VM_(operating_system)

   VM was also utilized in data centers converting from DOS/VSE to MVS and is useful when running mainframe AIX and Linux, platforms that were to become increasingly important. The current z/VM platform has finally achieved the recognition within IBM that VM users long felt it deserved.

9. z/OS - Wikipedia

   en.wikipedia.org/wiki/Z/OS

   An IBM System Z10 mainframe computer on which z/OS can run. z/OS is a 64-bit operating system for IBM z/Architecture mainframes, introduced by IBM in October 2000. [2] It derives from and is the successor to OS/390, which in turn was preceded by a string of MVS versions.
