Identify the correct definition of Priority queue.
Difficulty: Medium
About this MCQ
This Medium Data Structures question asks: Identify the correct definition of Priority queue. The correct choice is B. An abstract data structure where each element has a priority, and elements are served according to that priority rather than arrival order.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Data Structures items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Data Structures so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Data Structures item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. A node structure that contains a pointer or reference to another node of the same type, forming the basis of linked structures.
Why not A: “A node structure that contains a pointer or reference to another node of the same type, forming the basis of linked structures.” is not An abstract data structure where each element has a priority, and elements are served according to that priority rather than arrival order..
- B. An abstract data structure where each element has a priority, and elements are served according to that priority rather than arrival order. ✓
- C. A collision resolution technique in hashing that searches sequentially for the next open slot in the table.
Why not C: “A collision resolution technique in hashing that searches sequentially for the next open slot in the table.” is not An abstract data structure where each element has a priority, and elements are served according to that priority rather than arrival order..
- D. A way of representing a graph using a 2D matrix where each cell indicates whether an edge exists between two vertices.
Why not D: “A way of representing a graph using a 2D matrix where each cell indicates whether an edge exists between two vertices.” is not An abstract data structure where each element has a priority, and elements are served according to that priority rather than arrival order..
Correct answer
B. An abstract data structure where each element has a priority, and elements are served according to that priority rather than arrival order.
Explanation
An abstract data structure where each element has a priority and elements are served according to that priority rather than arrival order option B is the accepted answer to Identify the correct definition of Priority queue Option A A node structure that contains a pointer or reference to another node of the same type forming the basis of linked structures is a different value from An abstract data structure where each element has a priority and elements are served according to that priority rather than arrival order Option C A collision resolution technique in hashing that searches sequentially for the next open slot in the table is a different value.
