What does B-tree refer to?
Difficulty: Hard
About this MCQ
This Hard Data Structures question asks: What does B-tree refer to? The correct choice is A. A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases.. 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 self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases. ✓
- B. A matrix in which most of the elements are zero, often stored using specialized structures to save memory.
Why not B: “A matrix in which most of the elements are zero, often stored using specialized structures to save memory.” is not A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases..
- C. A data structure that allows insertion and removal of elements from both the front and the back.
Why not C: “A data structure that allows insertion and removal of elements from both the front and the back.” is not A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases..
- D. An array-like data structure that automatically resizes itself as elements are added or removed.
Why not D: “An array-like data structure that automatically resizes itself as elements are added or removed.” is not A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases..
Correct answer
A. A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases.
Explanation
A self-balancing tree data structure that maintains sorted data and allows searches insertions and deletions in logarithmic time commonly used in databases option A is the accepted answer to What does B-tree refer to Option B A matrix in which most of the elements are zero often stored using specialized structures to save memory is a different value from A self-balancing tree data structure that maintains sorted data and allows searches insertions and deletions in logarithmic time commonly used in databases Option C A data structure that allows insertion and removal of elements from both the front and the back is a different value from A self-balancing tree data structure.
