Which DBMS component handles disk space allocation?
Show Hint
File Manager handles physical storage while Buffer Manager handles main-memory buffers.
Updated On: Jun 25, 2026
- Buffer manager
- File manager
- DDL interpreter
- Query processor
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
A DBMS is composed of several internal modules responsible for different tasks.
The File Manager manages storage structures and disk allocation.
Step 1: Understand File Manager.
The File Manager is responsible for:
• Disk space allocation
• File organization
• Maintaining file structures
• Free space management
Step 2: Analyze other components.
Buffer Manager manages memory buffers. DDL Interpreter processes schema definitions. Query Processor executes database queries.
Step 3: Identify the correct component.
Since disk space allocation is a storage management task, \[ \boxed{\text{File Manager}} \] is the correct answer.
