(Add synchronization to your solutions to HW 3 to eliminate all of the race conditions. You should not remove any of the sleep() commands that you used to produce the race conditions, but simply add the necessary mutex synchronization calls. Your writeup should include high level pseudocode explaining the logic of your synchronization strategy using ordinary semaphores (init, p(), v()); your implementation should use the synchronization primitives of the programming API you are using (Posix & Win32). Submit design documentation, wellXcommented source code & annotated output for this part of the assignment.
Fault tolerance Machine failures, Communication faults, storage device crashes, and decays of storage media should be tolerated by the system to some extent. A fault tolerant s

What are the main advantages of the microkernel approach to system design? Benefits typically contain the following (a) Adding a new service does not require modifying the
What is banker's algorithm? Banker's algorithm is a deadlock avoidance algorithm that is applicable to a resource-allocation system with multiple examples of each resource type
Deadlock Detection and Recovery It's a method of permitting the system to enter a deadlock state, detect it and then recover. Deadlock detection : Is the process of
explain any four types of operating system feature and structure(design)
Several schemes available are as follows: Pipes : One-way communication process through which different process can interact. The problem is that the two processes could have
Since most of the programs require a lot of memory allocation/deallocation, we expect the memory management to be fast, to have low fragmentation, make good use of locality, and be
