AIM: To learn the various aspects of operating systems such as process management,

memory management, file systems, and I/O management

UNIT I PROCESSES AND THREADS

Introduction to operating systems – review of computer organization – operating system

structures – system calls – system programs – system structure – virtual machines.

Processes: Process concept – Process scheduling – Operations on processes –

Cooperating processes – Interprocess communication – Communication in client-server

systems. Case study: IPC in Linux. Threads: Multi-threading models – Threading issues.

Case Study: Pthreads library

UNIT II PROCESS SCHEDULING AND SYNCHRONIZATION

CPU Scheduling: Scheduling criteria – Scheduling algorithms – Multiple-processor

scheduling – Real time scheduling – Algorithm Evaluation. Case study: Process

scheduling in Linux. Process Synchronization: The critical-section problem –

Synchronization hardware – Semaphores – Classic problems of synchronization –

critical regions – Monitors. Deadlock: System model – Deadlock characterization –

Methods for handling deadlocks – Deadlock prevention – Deadlock avoidance –

Deadlock detection – Recovery from deadlock.

UNIT III STORAGE MANAGEMENT

Memory Management: Background – Swapping – Contiguous memory allocation –

Paging – Segmentation – Segmentation with paging. Virtual Memory:Background –

Demand paging – Process creation – Page replacement –Allocation of frames –

Thrashing. Case Study: Memory management in Linux

UNIT IV FILE SYSTEMS

File-System Interface: File concept – Access methods – Directory structure –Filesystem

mounting – Protection. File-System Implementation : Directory implementation

– Allocation methods – Free-space management – efficiency and performance –

recovery – log-structured file systems. Case studies: File system in Linux – file

system in Windows XP

UNIT V I/O SYSTEMS

I/O Systems – I/O Hardware – Application I/O interface – kernel I/O subsystem –

streams – performance. Mass-Storage Structure: Disk scheduling – Disk management –

Swap-space management – RAID – disk attachment – stable storage – tertiary storage.

Case study: I/O in Linux
