4. Components of an Operating System
Operating system – part of the computing system that manages all of the hardware and all of the software
Controls every file, device, section of main memory & every nanosecond of processing time
Memory manager
Processor manager
Device manager
File manager
Operating system consists of
Understanding Operating Systems

5. Subsystems Must Work With Each Other

6. Tasks Performed by Each Subsystem
Monitor its resources continuously
Enforce the policies that determine who gets what, when and how much
Allocate the resource when appropriate
Deallocate the resource (reclaim it) when appropriate
Understanding Operating Systems

7. Machine Hardware Memory chips
Input/output devices (monitor, keyboard, printer)
Storage devices (disks, magnetic tape, card readers, drums)
Central Processing Unit (Arithmetic Logic Unit, registers, internal control, bus control)
Understanding Operating Systems

8. Types of Operating Systems
Batch (simple and multi-programmed)
Interactive (time-sharing)
Real-time systems
Hybrid systems (combination of batch and interactive)
Parallel (tightly coupled)
Distributed (loosely coupled)
