Unless stated (or implied) otherwise, you should make the following assumptions: The OS manages a single uniprocessor (single core) All memory is byte addressable Page table and page directory entries require 4 bytes Data is allocated with optimal alignment, starting at the beginning of a page Assume leading zeros can be removed from numbers (e.g., 0x06 == 0x6). Hex numbers are represented with a proceeding “0x” The following might help you with some calculations: 0x100 = 28 = 256 210 = 1024 212 = 4096 210 bytes = 1KB 220 bytes = 1MB   This exam has 60 questions.  Each question has the same number of points.   Good luck!
