Answer: In external hashing the hash table is in disk where each slot of the page table holds multiple entries which refers to pages on the disk organised in the form of buckets.

B-trees are self balancing trees which contains sorted data and allows insertion, deletion, traversals

Traversal is the process of visiting the nodes of the tree data structure.

Explanation:

External hashing is different from internal hashing and it refers to concepts in database management systems. Internal hashing stores only single record maintained in page table format, whereas external hashing holds multiple entries.

B-trees are generalisation of binary trees where it can have more than 2 children.

Traversal of trees helps in insertion, deletion, modification of nodes in tree data structure

O How basic blocks are identified and how the blocks are used to construct control flow graphs
OLEGan [10]

Basic blocks are identified  because they are known to be a straight line that is known also as a code sequence that tends to have no branches in regards to its in and out branches and its exception is only to the entry and at the end.

Note that  Basic Block is said to be a composition  of statements that is known to be one that often always executes one after other, and this is often done in a sequence.

<h3>How do you create a flow graph from the basic blocks?</h3>

Flow graph  is gotten by:

  • Lets Block B1 be the initial node and also Block B2 will tend to follows B1, so from B2 to B1 there is seen a kind of an edge.

Note that the first task is for a person to partition a sequence of three-address code and this is done into basic blocks.

Hence, Basic blocks are identified  because they are known to be a straight line that is known also as a code sequence that tends to have no branches in regards to its in and out branches and its exception is only to the entry and at the end.
