homework for Advanced Computer Architecture

My prof. is so sensitive about plagiarism
Please make sure that all my work is unique

It is for Advanced Computer Architecture class

I need you to answer the attachment question as you can see I will choose (B. Ph.D program) and I choose to be interviewed with D. Ph.D. Program Committee.

Many of my friends do the same assignment and I think some of them already contacted you to do that so, please no plagiarism and I need you to write references

It is at least 2 pages single-spaced 12 font

And this is our book “Computer Architecture: A Quantitative Approach Fifth Edition”

My project was about “Cache Coherence protocols: Snoopy and Directory based protocol”
