My student said that the abstract designs of the three primary page replacement algorithms (FIFO, LRU, and optimum) are similar, with the exception of the characteristic utilized to choose the page to be replaced. I was of the contrary view. (a) Which characteristic of the FIFO algorithm are you referring to? (c) What is the name of the algorithm you're referring to? What is the LRU algorithm and how does it function? What is the pptimal algorithm in its simplest form? The general method for these page replacement schemes must be stated in the specification (b).
