Definition: Cluster


Cluster is a basic allocation unit on a hard drive. It is a group of contiguous sectors. The cluster size (number of sectors per cluster) varies with the storage media and is fixed at time of format. At least one cluster is allocated to each file, regardless of the file's size, that is stored in the DOS environment.
