Assume in a Virtual Memory system, a program needs 10 pages with page numbers 0 to 9 and each page is 4  words and the program is allocated 3 page frames: a, b, and c. The word trace for 26 memory accesses by the program  are listed below. Use a table to compare the three replacement  policies: LRU, OPTimal, and FIFO, by calculating and comparing the hit rate of each policy for these 26 memory  accesses.

Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:
