Defragmentation software is a utility program essential for maintaining a computer's hard drive efficiency. Over time, files on a disk become fragmented, meaning that different parts of a file are scattered across the disk, leading to slower access times. Defragmentation software reorganises the data by rearranging the fragments of files and free space on the hard drive to put them into contiguous blocks, which helps in speeding up data retrieval and improving overall system performance. For GCSE Computer Science students, understanding defragmentation is crucial as it highlights concepts related to data storage efficiency and the inner workings of computer maintenance.
