  3. The programmer may perhaps adjust the number of KLTs
  4. Process comprise the user's address space, process control block and stack
  5. User-level (threads library) threads invisible to the OS are the interface for application parallelism
  6. Kernel threads the unit that is able to be dispatched on a processor
  7. Lightweight processes (LWP) every LWP supports one or more ULTs and maps to exactly one KLT.
