UNIX and Linux ?have four components defining the file system. Identify and give a brief description of each.

What will be an ideal response?

UNIX/Linux has four components defining the file system: boot block, superblock, inode block, and data block.The boot block contains the bootstrap code--instructions for startup.?The superblock contains vital information about the system and is considered part of the metadata.It specifies the disk geometry and available space and keeps track of all inodes. It also manages the file system, including configuration information, such as block size for the drive, file system names, blocks reserved for inodesm and volume name.?Inode blocks contain the first data after the superblock. An inode is assigned to every file allocation unit. As files or directories are created or deleted, inodes are also created or deleted.??The data block is where directories and files are stored on a disk drive. This location is linked directly to inodes. A data block is equivalent to a cluster of disk sectors on a FAT or NTFS volume.
