Answer from cs61c-ep (Hao Wen Vivian Chong 15826235) for Question 2
Because pages are allocated in fixed-size chunks, we do not need to find a contiguous block of memory for which to allocate to a program; instead, we only need to worry about finding the sufficient number of pages in main memory. What's good about larger pages is that it reduces the amount of misses by taking advantage of spatial locality.
