Appendix C

Glossary

AFP	AppleTalk Filing Protocol\ is the standard way Mac OS 9 and earlier versions share
	files across the network.
CIFS	Common Internet File System, a standard protocol that Windows users use to share
	files across the network. Mac OS X also has the capability to share files using CIFS.
FTP	File Transfer Protocol, a common protocol adopted by many OS to enable remote file
	download and upload for public sharing.
HTTP	Hypertext Transfer Protocol, the protocol Web browsers use to connect to Web
	servers for file access, typically Web pages.
HTTPS	HTTP with SSL encryption is used where secure Web access is desired.
NFS	Network File System, a common way Unix and Linux systems share files by making
	remote file systems appear to reside locally.
Quota	Amount of volume space allocated to a particular user or group account, or to a
	particular share. The user, group, or share with a set quota cannot exceed disk usage
	beyond this limit. Quota is typically specified to ensure that no one user, group, or
	share abuses the available storage space.
RAID	Redundant Array of Independent Disks. Basically it is a method of storing data on
	multiple disks in a way that if one disk fails, data can still be accessed from the other
	disks. A RAID level selects how data will be kept redundant, the most popular of
	which are levels 0, 1, and 5. Contrary to the RAID acronym, RAID level 0 does not
	provide any redundancy. For more information, see Appendix A, “RAID Levels
	Simplified.”.
Share	A folder on a NAS volume that can be shared among different network file services
	such as CIFS for Windows, AFP (AppleTalk File Protocol) for Macs, NFS for Unix/
	Linux, FTP, and HTTP. Access to the share can be customized on a user or group or
	host-level basis.
Snapshot	An instantaneous, non-changing, read-only image of a volume. Snapshots are useful
	for backups.While a snapshot is being taken, the original volume can continue to
	operate normally. Snapshots can also be utilized as a temporary backup in case of
	viruses. Files can be restored from the snapshot volume if current files are corrupted.
Volume	A file system built on top of a RAID set. This file system consists of shares that are
	made available through various network file services.
X-RAID	NETGEAR patent-pending Expandable RAID technology.
