Answer: Physical location
Explanation:
If we place records from, different tables in adjacent physical location, it would increases efficiency of a databases as, database consolidates records from previously store in separate files into a common file. Databases are fast and efficient when they are dealing with large data. When all the information is stored in multiple physical location it is also known as distributed database, as physical location helps to provide the physical and logical path and also protect from default locations in the database.
Answer:
The answer is <em>since both ip addresses are not within the same subnet, only router can be used for the two computers to communicate together.</em>
Explanation:
From the statements in the question, since the two ip addresses are not on same subnet value i.e 172.31.210.10/24 and 172.31.209.122/24 then both computers cannot communicate except a router is used for network connections for the two different subnets as they are not on the same network.
Explanation:
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
