Fragmentation and Defragmentation
Posted by (0) Comment
Fragmentation deals with hard drives, more specifically the filesystem on hard drives. Almost all filesystems fragment, but some are better than others. But what exactly is fragmentation? Hard drives are composed of platters of magnetic media ( think of an old LP record) The files take up a block of space , if there is free space on the drive , the block are contiguous with each other. Perhaps a visual explanation would help here. And this is a basic explanation of the internals of a file system.
