What is memory fragmentation and how does it affect performance?

What is memory fragmentation and how does it affect performance?

Memory fragmentation occurs when free memory is split into small, non-contiguous blocks, making it difficult to allocate larger chunks. This can lead to inefficient memory usage and decreased performance.

Can you explain the difference between internal and external fragmentation?

Sure! Internal fragmentation happens when allocated memory blocks are larger than necessary, wasting space. External fragmentation occurs when free memory is scattered, preventing allocation of larger blocks.

How can memory fragmentation be reduced?

Memory fragmentation can be reduced through techniques like compaction, using memory pools, or employing better allocation algorithms.

What are the signs of memory fragmentation in a system?

Signs include slow performance, increased allocation failures, and higher memory usage than expected.

Is memory fragmentation a problem in modern operating systems?

Yes, it can still be a problem, especially in systems with limited memory resources or when running many applications simultaneously.
