 | | VM/CMS (Virtual Machine/Conversational Monitor System, originally called CP/CMS when it first appeared) is a bundled pair of operating systems used on IBM System/360, System/370, System/390, zSeries, and System z9 mainframes (and compatible systems). |
 | | In summary, VM is a powerful Operating System, that can run multiple guset operating systems, or allow multiple users to access their own ‘virtual’ computer. |
