Physical storage objects:
- The basic physical storage device that ultimately stores your data is the hard disk.
- When you install your operating system, hard disks are formatted as part of the installation program.
- Partitioning is the basic method of organizing a disk to prepare for files to be written to and retrieved from the disk.
- A partitioned disk has a prearranged storage pattern that is designed for the storage and retrieval of data.
(The book then goes into the basic disk layouts that Sun, HP-UX, AIX, and Linux uses.)
