Height of a binary tree is the longest path from it’s root to any of its leaves. With number of nodes as n, Max height possible: n-1 (skewed binary trees) Min height possible: $floor(\log_{2}n)$ (perfect binary trees) An AVL tree is a height-balanced binary tree where the difference between the heights of the left subtree and the right subtree cannot exceed 1 for all nodes.

Answered: memory management

Here the overhead is reading a word from the page table and we need to reduce the overhead. So , when access is sequential memory access then (new mean ovehead time) = TLB hit rate (TLB access time) + TLB miss rate (TLB access time +Page table access time ) 200 = h(100)+(1-h)(100+500) h=0.8 when access is parallel memory access then (new mean ovehead time) = TLB hit rate (TLB access time) + TLB miss rate (Page table access time ) 200 = h(100)+(1-h)(500) h=0.75 [...]
