Consider a paging system with the page table stored in memory. If a memory reference takes $200$ nanoseconds, how long does a paged memory reference take? If we add a Translation Lookaside Buffer (TLB) and $75$ percent of all pagetable references are ... memory reference time? Assume that finding a pagetable entry in the TLB takes $20$ nanoseconds, if the entry is present.

A file $F$ holds the nonzero elements of two large $n \times n$ matrices, $a$ and $B$. The matrix entries are sorted as triplets $(i, j, value)$, where $value$ is the $(i,j)$th element of a matrix. The file first stores the element of ... no, give reasons. If yes, provide a solution. Clearly explain the data structure and how you are going to store, retrieve, and add the elements.
