- What is the argument behind, "What operating system, when it crashes,
- leaves the computer operational?" I am asking you to think this over
- before you continue to read. What is the essence of the argument? I
- would like you to respond to this without continuing reading, and do
- not alter your response after you continue reading-- you don't have to
- post the response, it's for you.

- "What operating system, when it crashes, leaves the computer operational?"
-
- An operating system manages resources (CPU time, memory space, file
- storage space, I/O devices and so on). The operating acts as the
- manager of these resources and allocates them to specific programs and
- users as necessary for the latter's tasks. It controls these
- resources,i.e., execution of programs (cpu), improper use of these
- resources (an application trying to access previliged memory, for
- instance), and more emphasis is usually put on control of I/O devices.
- On the highest level of abstraction, the operating system brings life
- into the dead hardware. The Hard-drive is a piece of metal and
- magnetic surface without instructions, the memory is useless without
- means to access it, it is the operating system that connects these two
- and all other parts of the computer into a single operating unit--
- hence the name "operating system."
-
- It follows directly from the definition of an operating sysem (any
- definition as long as it is reasonably detailed, a few lines of
- definition) that when the operating system dies, crashes, taken out of
- control the hardware is dead, disjointed and useless. The essence of
- the argument, "What operating system, when it crashes, leaves
- the computer operational?" now clearly follows. If it were the
- operating system that crashed the computer would be a collection of
- metal objects of relatively high complexity completely disjointed, and
- useless. [Hardly the case with windows]
-
- There is no contradiction in any thing said so far in the posts. Even
- in VM where there are nested operating system this is true. If the
- CPM operating system crashes it leaves the virtual machine, which it
- was executing on, completely disjoint and non-operational. The
- physical machine on which CPM is running is still in good shape,
- because it's operating system, VM, was not touched.
