Outline for January 4, 2001

1.	Greetings and Felicitations!

a.	Go over class information handouts

2.	Operating System Functions

a.	I/O Functions: polling, interrupt-driven, DMA

b.	Process Functions: creation, deletion, synchronization, communication 

c.	Memory Functions: allocation, deallocation, management

d.	Secondary Storage Functions: data motion, address translation

e.	User Interface Functions: command interpreter, job control language

f.	Desireable Features: efficiency, reliability, maintainability, smallness

3.	Principles of Operating System Design

a.	Separation of Policy and Mechanism

b.	layering (THE: hardware, processor allocation and process synchronization, memory, console messages, I/O 
buffering, user programs, operator/console)

4.	Organization of Operating System

a.	monolithic: processes are subroutines 

b.	kernel: operating system calls are subroutines 

c.	client-server model: kernel just passes messages 

d.	virtual: give illusion all hardware is available; run regular operating systems on top

5.	Types of Operating Systems

a.	Distributed operating systems (architecture-driven)

b.	Multiprocessor operating systems (architecture-driven)

c.	Real-time operating systems (application-driven)

d.	Database operating systems (application-driven)
