Transcribed Image Text:
Suppose that you have an application for which you want to access stored data with as few memory accesses as possible. The size of the disk blocks on the system you are using are 4096 bytes (meaning that a memory access reads in 4096 bytes). Assume you use a B+ Tree with the following implementation details: - each node contains an 8-byte pointer to its parent as well as its and left and right siblings - internal nodes also have 8-byte pointers to each child - each element in the collection has a unique 4-byte integer key - each element in the collection has a 12-byte value associated with each key. a) What are M and L? b) Suppose there are 500,000,000 elements stored in the B+ Tree. How many levels does the tree have? (A tree with just a root would be considered one level). C) How many elements could a tree with the same height hold? d) What is the general equation for the number of elements a B+ tree can hold, based on M, L, and the height of the tree, h. (h is equal to the number of levels in the tree minus 1). Suppose that you have an application for which you want to access stored data with as few memory accesses as possible.
