what is fragmentation

Fragmentation refers to the phenomenon where a file or data is broken up into smaller pieces and scattered across different locations on a storage device. This can happen when a file is created, modified, or deleted over time, causing the storage space to become fragmented. Fragmentation can slow down the performance of a computer or device because it takes longer to access the scattered pieces of data. To optimize performance, it is recommended to regularly defragment the storage device to consolidate the scattered data and improve access times.
