Description: The fragmentation ratio is a measure that indicates the amount of fragmentation present in a memory system, calculated as the ratio of fragmented memory to total memory. Fragmentation refers to the situation where available memory is divided into small, non-contiguous blocks, making it difficult to efficiently allocate memory to running processes. A high fragmentation ratio can lead to inefficient memory usage, as there may be enough total memory available, but not sufficiently large contiguous blocks to satisfy memory requests from processes. This phenomenon can affect system performance, as it may cause processes to wait for the appropriate memory or even result in allocation errors. Therefore, managing fragmentation is a crucial aspect of memory management in computing systems, as excessive fragmentation can lead to suboptimal performance and the need for memory compaction operations to reorganize memory blocks and reduce fragmentation.
