Define FIFO Page Replacement Algorithm
This policy simply eliminates pages in the order they arrived in the main memory. By using this policy we simply remove a page based upon the time of its arrival in the memory. For instance if we comprise the reference string that is: 1, 2, 3, 4, 1, 2, 5, 1, 2, 3, 4, 5 and 3 frames (3 pages can be in memory at a time per process) after that we have 9 page faults as shown
Major page fault: If the page is not loaded in memory at the time the fault is stated, then it is named major or hard page fault. The handler in the machine requires to search a
Partitions and mounting A disk can be sliced into many partitions, or a partition can span multiple disks. Every partition can be either "raw", having no file system, or "cooke
Interrupts The hardware mechanism that enables a device to inform the CPU is called an interrupt. The basic interrupt mechanism works as follows. The CPU hardware has a wire kn
Problem: (a) Modern operating systems are interrupt driven. If there are no processes to execute, no I/O devices to service, and no users to whom to respond, an operating syste
What is page fault and what are the steps taken by the OS to remove page fault? A page fault is caused while a page that hasn't been brought into memory is being addressed. The
This assignment is based on Programming Project 6.40 in Silbershatz. Implement the ProducerXConsumer program according to the instructions for Project 6.40 for both Linux and Win32
Q. Consider the demand-paged computer system where the level of multiprogramming is currently fixed at four. The system was recently deliberate to determine utilization of CPU and
Differentiate between sequential access and direct access method?
Now let us present an implementation of a producer-consumer system using condition variables. This implementation works. dequeue() lock(A) while (queue empty) { wait(A, C)
