Consider a Table T with a key field k. A and B tree of order P denotes the maximum number of record pointers in a B tree. Assume K is 10 bytes long disk block size is 512 Bytes. Record pointer is 8 Bytes and block pointer size is 5 Bytes long in order for each P tree node to fit in a single disk block the maximum value of P.

= Suppose that we have a B and the size of the search key field V is equal to 10 bytes, the size of the data (record) pointer Pr 6 bytes, and the tree (block) pointer P is 5 bytes and the value of p (the order or the maximum number of a tree pointers in a node) is equal to 20 for an internal node. a) Calculate the block size (B) b) Suppose that we have a B- tree instead of B and based on the block size found in question (a), calculate the order (p) for an internal node in this case.
Subject code- rcs502 Consider a Table T with a key field k. A and B tree of order P denotes the maximum number of record pointers in a B tree. Assume K is 10 bytes long disk block size is 512 Bytes.

Assume that disk block size is 1024 bytes. A B+-tree is created on an attribute of length 12 bytes. Each tree pointer is 6 bytes long and each data pointer is 7 bytes long. Find the order n of B+-tree nodes.
S.N. 33. B+ Tree is primarily utilized for implementing dynamic indexing on multiple levels. Compared to B- Tree, the B+ Tree stores the data pointers only at the leaf nodes of the Tree, which makes search more process more accurate and faster. The following key values are inserted into a B+ - tree in which order of the internal nodes is 3, and that of the leaf nodes is 2, in the sequence given below. The order of internal nodes is the maximum number of tree pointers in each node, and the order of leaf nodes is the maximum number of data items that can be stored in it. The B+ tree is initially empty. 10, 3, 6, 8, 4, 2, 1 The maximum number of times leaf nodes would get split up as a result of these insertions is?
Suppose 1,000 Integer elements are generated at random and are inserted into a sorted linked list and a binary search tree (BST) separately. Considering the efficiency of searching for an element in the two structures, which of the following statements is true? The search operation on the list takes longer time because the numbers are not sorted. The search operation will take the same time in both structures. The search operation on the BST takes shorter time because it is relatively balanced. None of these. The search operation on the BST takes longer time because the numbers are not sorted.
2.Consider a polynomial that can be represented as a node which will be of fixed size having 3 fields which represent the coefficient and exponent of a term plus a pointer to the next term or to 0 if it’s the last term in the polynomial. Then A = 11x4 -2x is represented by fig below A 11 4 -2 1 0 Represent the following polynomials in linked list form P = G – 3L +2F
Correct and detailed answer will be Upvoted. Thank you! Q. If a B+ tree file header record is 256 bytes, and sequence set blocks are 100 bytes, what is the byte offset for a RBN of {N} (assuming the first sequence set block has an RBN of 1)?
Suppose we are building a B-Tree. Pages are 4008 bytes. A key value takes 8 bytes, and a pointer to a tree node or a record takes 8 bytes. a) What is the maximum number of keys in each node? b) Calculate the maximum number of pages N, which can be indexed with anindex file with height, h=2 and m keys (m is calculated in part a)? c) How many I/O operations are required for searching through N pages using a sorted file (N is calculated in part b)?.
In a database file structure, the search key field is 14 bytes long, the block size is 512 bytes, a record pointer is 8 bytes and a block pointer is 7 bytes. The largest possible order of a non-leaf node if B+ tree implements this file structure is
8. Given a circular queue implemented in an array of size six and can accommodate a maximum of five elements with Front pointing to one element counterclockwise from the location of the front element in the queue and Rear pointing to the last inserted element in the queue. Also given, Front = 1; Rear = 5 Queue: A, B, C, D with What will happen after an element 'P' is inserted in to the queue and an element is deleted from the queue? Front = 2; Rear = 6;with Queue: B,C,D,P %3D Front = 2; Rear = 0 with Queue: A,B,C,D,P %3D Front = 2; Rear = 0 with Queue: B,C,D,P Front = 2; Rear = 6 with Queue: A,B,C,D,P %3D
Question 12 In the context of Single Linked List (SLL), which one of the following is NOT correct? On average, searching in SLL takes O(n) time In SLL, a pointer (reference) head points to the first node in the list c In general, searching in SLL is slower than searching in arrays The SLL can be traversed in the reverse direction using the backward links d.
An operating system follows a variable memory partitioning model. The system keeps track of empty blocks in a linked list in the order of their address, where each node stores the size of next empty block in the memory. Say that current state of the memory is hold by the linked list shown below, which tells that there are currently four empty blocks in the memory, and the size of first block is 12 byte etc.
