Extracted text: Assume that a computer system is having 4-page frames for holding process pages in the main memory. The page reference string is mentioned below. BECAEFIHGCDZFRHIJKABCRPWSRTUZABE Assume that all the page frames are initially empty. Compute the total number of page faults and page hits that will occur while processing the page reference string using the FIFO and Optimal page replacement policy. State which algorithm will provide a better result for the above mentioned string.
