OPERATING SYSTEMS - OS
ALL TOPICS TO COVER IN OS
> Functionality and design of OS
> Structuring methods
(monolithic, layered, modular, micro-kernel models)
> Abstractions, processes, resources –
Influence of security, networking, and multimedia.
> Protection: User/Kernel modes
> Structures (Process Control Block, Ready List etc.)
> *Process creation
> *Threads: User level, kernel level threads and thread models.
> *Processes Scheduling
> *CPU Scheduling: Pre-emptive, non-pre-emptive
> *Multiprocessor scheduling
> *Deadlocks – Resource allocation and management
> *Deadlock handling mechanisms: prevention, avoidance, detection, recovery.
> *Synchronization
> Implementing synchronization primitives (*Peterson’s solution, *Bakery algorithm, synchronization hardware)
> *Semaphores
> Monitors: Solution to Dining Philosophers problem
> Multiprocessors and Locking – Scalable Locks – Lock-free coordination.

Container virtualization
> File system interface (access methods, directory structures)
> File system implementation
> *File system recovery
> *Disk structure and attachment
> *Disk scheduling algorithms (seek time, rotational latency
based)
> *System threats and security
> Policy vs mechanism
> System protection: Access matrix
> OS: performance, scaling, future directions in mobile OS
