Outline for January 4, 2001

1. 1. Greetings and Felicitations!
   1. Go over class information handouts
2. Operating System Functions
   1. I/O Functions: polling, interrupt-driven, DMA
   2. Process Functions: creation, deletion, synchronization, communication
   3. Memory Functions: allocation, deallocation, management
   4. Secondary Storage Functions: data motion, address translation
   5. User Interface Functions: command interpreter, job control language
   6. Desireable Features: efficiency, reliability, maintainability, smallness
3. Principles of Operating System Design
   1. Separation of Policy and Mechanism
   2. layering (THE: hardware, processor allocation and process synchronization, memory, console messages, I/O buffering, user programs, operator/console)
4. Organization of Operating System
   1. monolithic: processes are subroutines
   2. kernel: operating system calls are subroutines
   3. client-server model: kernel just passes messages
   4. virtual: give illusion all hardware is available; run regular operating systems on top
5. Types of Operating Systems
   1. Distributed operating systems (architecture-driven)
   2. Multiprocessor operating systems (architecture-driven)
   3. Real-time operating systems (application-driven)
   4. Database operating systems (application-driven)
