WHAT IS AN OPERATING SYSTEM?
WHAT DOES OS PROVIDE: ROLE
Abstraction: Provide standard library for resources What is a resource? Anything valuable (e.g., CPU, memory, disk) What abstraction does modern OS typically provide? CPU: process and/or thread Memory: address space Disk: files
WHY SHOULD OS DO THIS?
Advantages of OS providing abstraction? Allow applications to reuse common facilities Make different devices look the same Provide higher-level or more useful functionality Challenges What are the correct abstractions? How much of hardware should be exposed?
WHY SHOULD OS DO THIS?
Advantages of OS providing resource management? Protect applications at a common layer Provide efficient access to resources (cost, time, energy) Provide fair access to resources Challenges What are the correct mechanisms? What are the correct policies?
OPERATING SYSTEM ROLES SUMMARY
Two main roles
- Abstraction
- Resource management
