I was of the opposite opinion.(a) What is the property of the FIFO algorithm that you are referring to? (b) What is the name of the algorithm that you are referring to? What is the LRU algorithm and how does it work? What is the pptimal algorithm in its most basic form?The general algorithm for these page replacement strategies should be included in the specification (b).According to my student, the abstract design of the three basic page replacement algorithms (first-in, first-out (FIFO), and last-in, last-out (LRU), and optimum) is similar, with the only difference being the characteristic that is utilized to determine the page to be replaced. Personally, I thought the exact opposite.(a) When you say that the FIFO algorithm has this quality, what exactly do you mean? What is the name of the algorithm you're referring to in (b)? Just what is the LRU algorithm, and how does it function? In its simplest form, what is the pptimal algorithm?It is recommended that the specification contain the general method for these page replacement schemes (b).
