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
