Example text

Larger volumes use larger cluster sizes. For hard disk volumes, each cluster ranges in size from 4 sectors (2,048 bytes) to 64 sectors (32,768 bytes). In some situations, 128-sector clusters may be used (65,536 bytes per cluster). The sectors in a cluster are continuous, so each cluster is a continuous block of space on a disk. In a cluster, any remaining space is wasted. This space is known as slack space. If the cluster size is large, there will be less fragmentation, but there will be more wasted space.

Slack Space Slack space is the area of a disk cluster between the end of the file and the end of the cluster. If the size of a file is less than the cluster size, a full cluster is still assigned to that file. The remaining space remains unused and is called slack space. Hard Disks 1-11 When a greater number of files are stored on a disk with a large cluster size, a lot of the disk space is wasted as slack space. DOS and Windows file systems use fixed-size clusters. DOS and older Windows versions use a 16-bit file allocation table (FAT16) that results in a large cluster size for large partitions.

It supports a B-tree structure for directories. • It has a centrally located root directory. ISO 9660 is a standard published by the International Organization for Standardization. It describes a file system for CD-ROMs and DVDs that supports different operating systems for the easy exchange of data. JFS Journaled File System IBM created this file system. It was released with the first version of AIX. The goals of creating this file system were: • To provide scalability • To support computers that have more than one processor • To have a more portable file system • To provide the capability of running multiple operating systems LFS Log-structured File System The following features of LFS are borrowed from UFS: • Indirect paths • Inodes • Directory formats LFS divides the disk into smaller segments; the segments are filled from the bottom to the top.
