cluster

An elementary unit of allocation of a disk made

up of one or more physical {blocks}.

A {file} is made up of a whole number of possibly

non-contiguous clusters. The cluster size is a tradeoff

between space efficiency (the bigger is the cluster, the

bigger is on the average the wasted space at the end of each

file) and the length of the {FAT}.
