z/OS is a 64-bit operating system that runs on IBM's traditional mainframe hardware, also known as System z.

z/OS, along with zLinux, zTPF, z/VSE and z/VM, is an operating system which runs on IBM's System z hardware.

This tag should be used when asking questions related to the specific operating system z/OS, associated tags may be mainframe, cics or db2 (provided you're talking about the mainframe versions of those products).
