1. Course Introduction CSSE 332 Operating Systems Rose-Hulman Institute of Technology

2. Intro to Course Survey of Operating Systems concepts Several chapters in Text (12) Lots of programming in C Programming lab each week 1 bigger team project

3. Course Mechanics: Schedule When is Homework 1 due again? What resources are we using today? What topics are we covering today? What time of day is each assignment due?

4. Today’s content: Intro to OS Computer platform consists of a collection of hardware resources Computer applications are developed to perform some task using those resources Inefficient for applications to be written directly for a given hardware platform, why?

5. How does an OS Help? Operating system provides a convenient to use, feature rich, secure, and consistent interface for applications to use OS provides a uniform, abstract representation of resources that can be requested and accessed by application

6. Fundamental job of modern OS The fundamental task of any modern operating system is process management. OS must: Allocate resources to processes Enable processes to share and exchange info Protect the resources of a process from other processes Enable synchronization among processes

7. Processes A process is a program in execution; process execution progresses in sequential fashion. Can be characterized by its trace. A process requires resources, which are managed by the operating system The OS interleaves the execution of several processes to maximize processor utilization OS supports Inter-Process Communication (IPC) and user creation of processes

8. Agenda for rest of week Basic intro to LINUX and C Complete LINUX installation by Wednesday Complete homework 1 Read chapters 1 and 2
