Question:
Which of the following is not a valid file allocation method?
Which of the following is not a valid file allocation method?
Show Hint
Three real methods are Contiguous, Linked, and Indexed. One option is none of these.
Updated On: Jul 2, 2026
- Indexed Allocation
- Contiguous Allocation
- Logical Allocation
- Linked Allocation
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: The standard file allocation methods used by operating systems are Contiguous, Linked, and Indexed allocation.
Step 2: Contiguous keeps a file in one continuous run of blocks. Linked chains blocks with pointers. Indexed keeps all block pointers in a single index block.
Step 3: There is no method named Logical Allocation in file systems. It is not one of the three recognised techniques.
Step 4: So the option that is not a valid method is (C) Logical Allocation.
Step 2: Contiguous keeps a file in one continuous run of blocks. Linked chains blocks with pointers. Indexed keeps all block pointers in a single index block.
Step 3: There is no method named Logical Allocation in file systems. It is not one of the three recognised techniques.
Step 4: So the option that is not a valid method is (C) Logical Allocation.
