A file system is a logical collection of files and directories contained in a partition. It can be treated as a single entity when you're making it available for use (mounting), checking it, and repairing it.
The three types of file systems supported by the Solaris 8 environment are disk based, memory based (pseudo), and network based. The Part I exam concentrates on disk-based file systems. The Part II exam covers pseudo file systems (Chapter 16, “Pseudo File Systems and Swap Space”) and network-based file systems (Chapter 18, “Network File System”).
Disk-based file systems are stored on physical disks, CD-ROMs, DVDs, and floppy disks on the local system. Table 9.1 lists the disk-based file system formats.
