Question

In modern systems, management scheme that permits the physical address space of a process to be non-contiguous is:

• A. Dynamic loading
• B. Address binding
• C. Paging
• D. Partitioning

Hint:

Paging removes external fragmentation by allowing scattered memory allocation.

Answer 1

The Correct Option is C

Concept: Memory management schemes determine how memory is allocated to processes.

Step 1: Understand requirement. Non-contiguous allocation means:
• Process does not need continuous memory block
• Memory divided into fixed-size pages

Step 2: Analyze options.
• Dynamic loading → Loads program during execution
• Address binding → Maps addresses
• Paging → Divides memory into pages and frames (non-contiguous)
• Partitioning → Usually contiguous allocation

Step 3: Conclusion. Paging allows non-contiguous allocation. \[ \boxed{(3)\ \text{Paging}} \]
