- - - - Runs
      - No other program runs
    - - Processes are placed here
      - when a process is ready
        
        Ready queue
      - Device queue
        
        Attends a particular device
  - - - Selecting processes
        from the queue
  - - - These are sent to mass storage
      - Kept for later execution
    - - multiprogramming degree
  - - - which process to execute
  - - - Save state
      - Restore state
- - - - Producer
      - Consumer
    - - unbounded
      - bounded
  - - - Blocking
      - nonblocking
    - - Zero capacity
      - bounded capacity
      - unbounded capacity
- - - - new
      - running
      - waiting
      - Ready
      - Terminated
    - - Process state
      - Program counter
      - cpu registers
      - cpu-scheduling info
      - Memory-management info
      - Account information
      - I/O status information
    - - Multi-threading

        Process address
        
        Same to parent
        
        new program
        
        Parents execute
        
        Parallel to childen
        
        Synchronously
  - - - Cascading termination
    - - when it's done
        
        and the father doesn't
        know the state
    - - Processes who's father
        
        Is done executing
  - - - Shared memory
      - message passing
    - - Two types of process
        
        producer
        
        consumer
      - Two types of buffers
        
        unbounded
        
        bounded
    - - Direct communication
        
        requires
        
        naming
        
        symmetry
      - synchronization
        
        messages can be
        
        Blocking
        
        non-blocking
        
        Buffering
        
        Zero capacity
        
        bounded capacity
        
        undbounded capacity
- - - - three types of calls
        
        Small
        
        The ports queue is used
        
        Larger
        
        Section object
        
        Largest
        
        An API is used to read and write directly
- - - - Microsoft interface definition language
    - - Little endiand
      - Big endian
