Topic 1 Quiz – Introduction to Operating System

Operating System Structure
Study of operating system services, user and system interfaces, system calls, system programs, and the design and implementation approaches of operating systems such as layered architecture, microkernel, modules, and hybrid systems.

Batch Processing System
Concept of batch processing systems including how batch jobs are processed, advantages and disadvantages of batch systems, job control language, and the spooling process used in operating systems.

Process Management and Threads
Understanding processes and threads in operating systems including process states, process control, process scheduling, and communication in client-server systems.

Process Scheduling
Concepts of CPU scheduling including scheduling criteria and algorithms such as FCFS, Shortest Job First, Round Robin, and Priority Scheduling along with CPU burst cycle and dispatcher operations.

Deadlocks
Study of deadlock conditions in operating systems including causes of deadlocks, necessary conditions, prevention methods, avoidance algorithms, detection techniques, and recovery mechanisms.

Memory Management Techniques
Concepts of memory management including partition schemes, fragmentation, swapping, segmentation, paging, virtual memory, and demand paging techniques.

Storage and I/O System
Overview of storage systems and input/output management including disk structure, RAID architecture, mass storage systems, I/O hardware, and the role of operating systems in managing I/O operations.

File System
Introduction to file systems including file concepts, file attributes, file operations, file organization, disk space management, and file allocation methods.
