Fragmentation 1

Understanding memory fragmentation in operating systems

This is an easy foundational question on memory management that tests whether you can identify and name a core phenomenon in systems programming. Operating systems courses and systems interviews use it to establish baseline knowledge of how memory becomes fragmented during program execution.

The question probes your understanding of what happens to physical memory over time as processes are allocated, deallocated, and resized. It's a conceptual question rather than a coding or calculation problem—the focus is on recognizing the specific pattern of fragmentation that arises when many small free regions are scattered throughout memory, rather than consolidated into larger contiguous blocks.

• The distinction between different fragmentation patterns
• Why fragmentation matters for system performance and allocator design
