The concept in which a data structure consisting of nodes (vertices) connected by edges, used to represent relationships is best known as which of these terms?
Difficulty: Medium
About this MCQ
This Medium Data Structures MCQ checks one syllabus fact.
The question is: “The concept in which a data structure consisting of nodes (vertices) connected by edges, used to represent relationships is best known as which of these terms?”
The accepted answer is D. Graph. “The concept in which a data structure consisting of nodes (vertices) connected by edges, used to represent relationships is best known as which of these terms” is answered by Graph (option D). Option A (“Linked list”) does not match the stem; it is a near-miss used to catch incomplete recall of Graph. Option B (“Heap”) does not match the stem; it is a near-miss used to catch incomplete recall of Graph. Remaining alternatives (Doubly linked list) fall outside the same rule and should be eliminated once Graph is identified. Data Structures questions of this type reward precise definitions rather than approximate associations. Data Structures recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
- A. Linked list
Why not A: “Linked list” is not correct. The accepted answer is D. Graph. “The concept in which a data structure consisting of nodes (vertices) connected by edges, used to represent relationships is best known as which of these terms” is answered by Grap
- B. Heap
Why not B: “Heap” is not correct. The accepted answer is D. Graph. “The concept in which a data structure consisting of nodes (vertices) connected by edges, used to represent relationships is best known as which of these terms” is answered by Grap
- C. Doubly linked list
Why not C: “Doubly linked list” is not correct. The accepted answer is D. Graph. “The concept in which a data structure consisting of nodes (vertices) connected by edges, used to represent relationships is best known as which of these terms” is answered by Grap
