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        9

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    10

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            9

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         9

File-System Interface: File concept – Access methods – Directory structure –File-system 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            8

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
