It is free from unnecessary distractions.

Question

Question D.4: FIFO Page Replacement Consider the following page reference string: e, c, b, e, a, g, d, c, e, g, d, a Considering 4 frames, fill in the following table and then answer how many page faults would occur with the FIFO page replacement algorithm. RS: reference string; FO: frame 0, F1: frame 1, etc. Hint: all frames are initially empty, so your first unique pages will all cost one fault each.

Consider a system that uses a fixed-partition scheme, with equal partitions of size 2" bytes, and the main memory has 2¹8 bytes. A process table is maintained with a pointer to the resident partition for each resident process. How many bits are required for the pointer in the process table? Show all your steps.

Use the same semaphore notation shown above to describe how we can ensure the execution order of the following process execution graph: P6 P2 P7 P1 P3 P4 P5 Use all of the following semaphores in your answer: s1=0; s2=0; s3=0; s4=0; s5=0; s6=0;
