Q. Consider a distributed system with two sites A and B. Consider whether site A can distinguish among the following: a. B goes down. b. The link between A and B goes down.
What is reference string We evaluate an algorithm by running it on a definite string of memory reference and computing the number of page faults. The string of memory reference
