Sequence 4 CS240 1

Modern Operating Systems

  • Microkernel architecture
    • Assigns only a few essential functions to the kernel - Address spaces - Interprocess communication (IPC) - Basic scheduling Sequence 4 CS240 2

Modern Operating Systems

  • Multithreading
    • Process is divided into threads that can run concurrently - Thread - Dispatchable unit of work - executes sequentially and is interruptable - Process is a collection of one or more threads

Sequence 4 CS240 3

Modern Operating Systems

  • Symmetric multiprocessing (SMP)
    • There are multiple processors
    • These processors share same main memory and I/O facilities
    • All processors can perform the same functions Sequence 4 CS240 4

UNIX

  • Hardware is surrounded by the operating system software
  • Operating system is called the system kernel
  • Comes with a number of user services and interfaces - Shell - Components of the C compiler Sequence 4 CS240 8
