Explain the Novell NetWare    
NetWare doesn't really have the concept of processes in the architecture, as  the most closely associated element in the NetWare  environment to a process is the NetWare Loadable Module, or NLM, NLMs  are separate executables  that own data, code, and threads of execution.
They can be loaded by other NLMs by means of the spawn( ) family of commands.
