Why is the set?associative cache so popular?
What will be an ideal response?
A set associative cache gets the better of two worlds. First, it is very simple to design because it consists of, typically, two, four or eight direct?mapped caches in parallel. It is very easy to map data into a direct?mapped cache (because every item in main store has a fixed location in the cache). If two items have the same line address
in cache and that address is occupied in one of the caches, another member of the set can be used. In this case the associativity is only over 2, 4, or 8 locations, rather than millions. So, the cost is comparable with direct?mapped cache and the performance not too far from that of associative cache.

Why is one condition on line 4 “i is greater than -1”?
``` 1 for each j, from 1 to the length of A – 1 2 temp = A[ j ] 3 i = j – 1 4 while i is greater than -1 and A[ i ] is greater than temp 5 A[ i + 1 ] = A[ i ] 6 i— 7 A[ i + 1] = temp ``` A. -1 is not a valid index of an array B. if i has been set to -1, it means the array is already sorted C. if i is -1, we cannot do any more one-assignment swaps, so we must exit the loop D. if i is -1, it means the array cannot be sorted
