Explanation:

To divide a class C network into a maximum of 14 subnets -each capable of having up to 14 hosts , the subnet mask used should be : Correct Answer 255.255.255.240 A typical network class has 3 standard host ID sizes: Class A (24bits), Class B (16bits) and Class C (8bits). But in practice, these standard sizes are not economical. For instance, a 24bits host ID is capable of supporting a maximum of 2²¹ (2,097,152) host IDs. With few of these IDs in use, the rest becomes wasted resources. With subnetting however, we get to go beyond the standard host ID sizes and determine our own desired sizes. The basic meaning of a subnetwork is as the name suggests; a type of a smaller network gotten from the division of a network. They are created with the use of masking, just that this time around, the Host IDs are tweaked. For instance, the standard network masking for the Class C network, 207.17.5.0 is 255.255.255.0. This will give 2²¹ network IDs and (2⁸ – 2) hosts. 255.255.255.0 as used here is standard, but with subnetting, we could use 255.255.255.244.

Explanation:

The complexity of Bubble sort algorithm is Correct Answer O(n) Bubble sort has a worst - case and average complexity of О(n2), where n is the number of items being sorted. Most practical sorting algorithms have substantially better worst - case or average complexity, often O(n log n). When the list is already sorted (best - case), the complexity of bubble sort is only O(n). Class: Sorting algorithm Data structure: Array

Explanation:

To remove duplicate rows from the results of an SQL SELECT statement , the __ qualifier specified must be included. Correct Answer DISTINCT The SQL DISTINCT keyword is used in conjunction with the SELECT statement to eliminate all the duplicate records and fetching only unique records. There may be a situation when you have multiple duplicate records in a table. While fetching such records, it makes more sense to fetch only those unique records instead of fetching duplicate records. Syntax The basic syntax of DISTINCT keyword to eliminate the duplicate records is as follows − SELECT DISTINCT column1, column2,.....columnN FROM table_name WHERE [condition]

The term push and pop is related to the Correct Answer stacks Considered as a linear data structure, or more abstractly a sequential collection, the push and pop operations occur only at one end of the structure, referred to as the top of the stack. This data structure makes it possible to implement a stack as a singly linked list and a pointer to the top element.

Explanation:

what is the value of 'd' after this line of code has been executed ? double d = Math round ( 2.5 + math random () ); Correct Answer 3 The Math.random() method returns a number greater than or equal to 0 and less than 1 . Since we can then be sure that the sum of that number and 2.5 will be greater than or equal to 2.5 and less than 3.5, we can be sure that Math.round() will round that number to 3. So Option B is the answer.
