Glossary

AFP

: AppleTalk Filing Protocol, is the standard way Mac OS 9 and earlier 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 no one user, group,

or share abuses the available storage space.

RAID

: Acronym for

edundant

rray of

ndependent

isks. 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 disk(s). 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 info,

RAID Levels Simplified

Appendix A

: A folder on a NAS volume that can be shared amongst 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/group/host-level basis.

Snapshot

: An instantaneous, non-changing, read-only image of a volume. Snapshots are

useful for backups during which time the original volume can continue to operate

normally. Snapshots can also be utilized as a temporary backup against viruses.

Files can be restored from the snapshot volume if current files are corrupted.

Volume

: A filesystem built on top of a RAID set. This filesystem consists of sh ares that

are made available through various network file services.

X-RAID

: NETGEAR patent-pending Expandable RAID technology.
