Detailed explanation-1: -Also called an “allocation unit” or “file allocation unit, ” a cluster is the smallest unit of storage the operating system’s file system can manage. That means if a 1KB file is stored in a system with a 4KB cluster (see table below), the 1KB file takes up 4KB of disk space.
Detailed explanation-2: -File allocation table is a table for describing the allocation status of the clusters (the basic units of logical storage on a hard disk) in the file system and the link relationship between the file contents.
Detailed explanation-3: -A sector is the smallest physical storage unit on the disk, and on most file systems it is fixed at 512 bytes in size. A cluster can consist of one or more consecutive sectors – commonly, a cluster will have four or eight sectors.
Detailed explanation-4: -The allocation unit is the unit of storage a file can take up on the drive. This means that if you end up with a file one byte short of 4KB, it takes up 4KB on the drive. If you end up with a drive of 1 byte over 4KB, that file will take up two allocation units, consuming 8KB of drive space.
