SPRING 2015
CGS3763: Operating System Concepts
Lecturer: Professor Euripides Montagne
MoWeFr 10:30 AM - 11:20 PM

Day 1:

Lecture Topics: Operating System Topics, Textbook, Syllabus
Notes:

-Discussion about Homework 0.
	An operating system is an event-driven program. Handles system resources efficiently. It is an interface between user and system. Creates an environment for application programs to run.

-Discussion about Textbook.

-Discussion about Syllabus.
	Course learning outcomes:
	-Understand the interaction between the hardware and the operating system through the interrupt handling mechanism
	-Understand the concept of process and threads including their implementation
	-Understand process synchronization and deadlock
	-Understand CPU and disk scheduling
	-Have an understanding of memory organization and virtual memory
	-Understand file system

-> Algorithm:
	Global description: a series of steps to follow a recipe// A procedure or formula to solve a problem.

-> Program:
	Coded instructions to control the operation of a computer

////////How does a program and algorithm relate?
	We have to express the algorithm in a program language to solve the expression. When we compile the program and run the program in computer, it is a process.

-> Process.

Concurrency:
	Multiple processes running in the memory at the same time. -> Processor sharing. (Only one processor)

Virtual (Written??) Memory:
	A technique to run programs whose logical memory is larger than physical.
