Q. Suppose you have a computer system with a 48-bit logical address, page size of 16KB and 4 bytes per page table entry. If we have a 48MB program such that the entire program and all necessary page tables are in memory. Assume that each page table at diff level fits in a single page.How much memory is used by program, including its page tables?

The postorder traversal of a binary search tree is $25, 33, 30, 35, 42, 48, 40, 60, 58, 50$. The inorder traversal of the same tree is $25, 30, 33, 35, 40, 42, 48, 50, 58, 60$. What is the length of the longest path from one leaf to another leaf. (Note: Length of longest path means total number of nodes present in that path).

Consider a $3 \ \text{GHz}$ (gigahertz) processor with a three stage pipeline and stage latencies $\large\tau_1,\tau_2$ and $\large\tau_3$ such that $\large\tau_1 =\dfrac{3 \tau_2}{4}=2\tau_3$. If the longest pipeline stage is split into two pipeline stages of equal latency , the new frequency is __________ $\text{GHz}$, ignoring delays in the pipeline registers.
