I would venture to say that the operating system as we see it today is a package of a kernel, API, and system utilities. Some would argue that an operating system is only a kernel, and that wouldn't be wrong, just academic.

Is there a general consensus about what pieces or aspects of the software shipped with z/OS would be defined as the "operating system"? Thing is, I started thinking about what is an OS and I found myself having trouble defining it. For example, for Unix it seems to me that the OS would be the Kernel plus any loadable kernel modules that come shipped with the OS, like drivers for I/O and so on. It probably gets fuzzy when it comes to extensions to the OS. Maybe an equivalent to z/OS would be the shipped SVC's as opposed to vendor supplied? But for z/OS I wasn't how and where to draw the lines. Especially since z/OS comes also with a UNIX kernel. Any thoughts? I was just curious about this.
