Principles of Operating Systems

Notes FAT: File Allocation Table (FAT) is a computer file system architecture now widely used on
many computer systems and most memory cards, such as those used with digital cameras.
NTFS: NTFS is the standard file system of Windows NT, including its later versions Windows 2000,
Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista and Windows 7.
SCSI Hard Disk: A hard disk drive (HDD) is a non-volatile, random access device for digital
data. It features rotating rigid platters on a motor-driven spindle within a protective enclosure.

Zip Driver: The Zip drive is a medium-capacity removable disk storage system that was
introduced by Iomega in late 1994. Originally, Zip disks launched with capacities of 100 MB,
but later versions increased this to first 250 MB and then 750 MB.
