Outcome:

  • Apply optimization techniques for the improvement of system performance.
  • Ability to understand the synchronous and asynchronous communication mechanisms in their respective OS.
  • Learn about minimization of turnaround time, waiting time and response time and also maximization of throughput with keeping CPU as busy as possible.
  • Ability to compare the different OS
