 FRAGMENTATION Definition
We define FRAGMENTATION |
FRAGMENTATION - This occurs when a hard drive writes a file in multiple segments instead of in a physically contiguous area. A higher level of fragmentation means that most files are fragmented, and many files contain lots of fragments. A low level of fragmentation implies that more files are in one piece, and that if files are fragmented they are only in a few fragments. For example, say you have two files, file A and file B and you write them both to a hard drive. A low level of fragmentation may be represented by: AAAABBBB. A high level of fragmentation may be represented by: AABBABABA. Fragmentation is caused by deletion of small files, and then trying to fit larger files into the leftover spaces. Over time it is a common occurrence that is unavoidable in most file systems. |
