    Glossary 10/100 Base-TX Refers to running Ethernet on twisted pair cables, with a throughput of 10 or 100 Mbps. AppleShare File-sharing protocol used on Macintosh computers. Backup Domain Controllers (BDC) The BDC operates in a Windows NT Server domain. The BDC is a computer running the Windows NT Server that receives a copy of the NT domain's users and groups database, which contains all account and security policy information for the domain.
  • Page 66 Glossary Gateway A network device that acts as an entrance to another network. A gateway may also be any device that passes packets from one network to another network across the Internet. HTML HyperText Markup Language (HTML) is the set of ÒmarkupÓ tags, symbols, or codes inserted in a text Þle intended for display on a world wide web browser.
  • Page 67 Glossary Mirroring RAID level 1, or mirroring provides redundancy by writing identical data to each member disk of the array, leaving a ÒmirroredÓ copy on each disk. Mirroring remains popular because of its simplicity and high level of data availability. Level 1 operates with two or more disks that may use parallel access for high data-transfer rates when reading, but more commonly operate independently to provide high I/O transaction rates.
  • Page 68 Glossary Share A share is a shared directory thatÕs accessible via the network. Each share on the NASRaQ is simultaneously accessible to both Windows and Macintosh clients if enabled. Each share can have a unique set of access controls. The Server Message Block (SMB) protocol enables client applications in a computer to read and write to Þles on a computer network and to request services from server programs in a computer network for systems running Windows.
