Operating Systems

GATE CSE Operating Systems — processes, scheduling, synchronization, deadlock, memory, and file systems.

Learning outcomes

  • Compute waiting and turnaround times
  • Apply Peterson, semaphores, and monitors at MCQ level
  • Detect deadlock and use banker’s algorithm sketches
  • Solve paging and page-replacement questions

Overview

Operating Systems is a scoring GATE subject if you practise numerical scheduling, paging, and synchronization.

This hub covers the official topic groups: processes, CPU scheduling, concurrency, deadlock, memory, and files.

Draw Gantt charts and page tables until they are automatic.
