    Are my answers correct? Question 1 (Mandatory) (1 point) Saved Modern software systems are blurring the distinction between local files and web pages, which may be stored on a remote computer, so the amount of data that we might wish to search is virtually unlimited. Remarkably, the methods that we shall study can support search and insert operations on symbol tables containing trillions of items or more using only four or five references to small blocks of data. 1) True...

    [Index structure: B+ tree and B tree] (b). B+ tree index structure is said to be an improvement of B tree index structure. The most important distinction between them is that data record pointers exist in both internal and leaf nodes (i.e., blocks) for a B tree whereas only in the leaf nodes for a B+ tree. Explain why this distinction would make B+ tree a more efficient structure (in terms of index search speed) overall than a B tree...
