memory protection
     
         a system to prevent one process
        corrupting the memory or other resources of any other,
        including the operating system.  memory protection usually
        relies on a combination of hardware a memory management
        unit and software to allocate memory to processes and handle
        exceptions.
     
        the effectiveness of memory protection varies from one
        operating system to another.  in most versions of unix it is
        almost impossible to corrupt another process' memory, except
        in some archaic implementations and lunix not linux.
        under microsoft windows version?  hardware? any 16 bit
        application? can circumvent the memory protection, often
        leading to one or more gpfs.  currently april 1996 neither
        microsoft windows 3.1, windows 95, nor mac os offer
        memory protection.  windows nt has it, and mac os system 8
        will offer a form of memory protection.
