Which threading model maps each user thread to a kernel thread?

Explain Interprocess Communication (IPC) in operating systems. Your answer should include: Definition of cooperating processes Two IPC mechanisms: Shared Memory Message Passing Advantages and disadvantages of each method One real-world example where IPC is used.

Simplify the expression in terms of i:

A thread consists of:  

Consider the following processes: Process Arrival Time Priority CPU Burst I/O Burst CPU Burst P1 0 2 1 5 3 P2 2 3 3 3 1 P3 3 1 2 3 1 Assume Priority Scheduling where smaller priority value means higher priority. Tasks Draw the Gantt Chart for CPU scheduling. Calculate the waiting time of each process. Calculate the average waiting time. Calculate the average turnaround time.
