Run the simulation at More Page Replacement Algorithms web site (open the following link in a browser:

2.1. Use the following input sequence. 1 1 1 2 2 3 4 1 4 5 6 9 8 0 1 2 3 5 6 23 6 6 6 7. Use k=2, page frames as 3.

List the hit rates in all the different replacement algorithms and find which algorithms form the lower and upper bounds.

2.2. Use the following input sequence. 0 1 2 3 4 5 6 7 8 16 17 9 10 11 12 28 29 30 8 9 10 4 5 12 4 5. Find the page frame numbers for each of the following. List the optimal values for this case.

When FIFO algorithm performs better than LRU?

These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice. Unethical use is strictly forbidden.

The lower bound for page faults is 10 (the different no. of characters from the string).
The upper bound for page faults is 25 (because every page from reference causes a page fault).
Those happen...
