Term Definition disaster recovery disk DNS server (Domain Name System server) domain domain name Ethernet Ethernet address Ethernet port A strategy that allows a company to return to normal activities after a catastrophic interruption. Through failover to a parallel system or by restoration of the failed system, disaster recovery restores the system to its normal operating mode. A rigid platter, usually constructed of aluminum or mylar, with a magnetic surface that allows the recording of data, that is stored inside the drive. The server that maintains a mapping of all host names and IP addresses. Normally, this mapping is maintained by the system administrator, but some servers support dynamic mappings. A set of network resources in Windows NT and Windows 2000, such as users and groups of users. A domain may also include multiple servers on the network. To gain access to these network resources, the user logs into the domain. The ASCII name that identifies the domain for a group of computers within a network. The most widely installed local area network technology. 10Base-T Ethernet provide transmission speeds of up to 10 Mbps. Fast Ethernet or 100Base-T provides transmission speeds up to 100 Mbps and is typically used for LAN backbone systems, supporting workstations with 10Base-T cards. Gigabit Ethernet provides an even higher level of backbone support at 1000 Mbps (one Gigabit or one billion bits per second). The unique six-digit hexadecimal (0-9, A-F) number that identifies the Ethernet interface. The port that houses the network card to provide Ethernet access to the computer. event failover Any significant occurrence in the system that may require notifying a system administrator or adding an entry to a log. A strategy that enables one Ethernet port to assume the role of another port if the first port fails. If a port fails on a Snap Server, the second port assumes its network identity (if the two Ethernet cards have been configured for failover). When the port comes back online, the original identities are restored. Failover is possible only in a dual-Ethernet configuration. 119

disaster recovery
A strategy that allows a company to return to normal
activities after a catastrophic interruption. Through failover
to a parallel system or by restoration of the failed system,
disaster recovery restores the system to its normal operating
mode.
disk
A rigid platter, usually constructed of aluminum or mylar,
with a magnetic surface that allows the recording of data,
that is stored inside the drive.
DNS server (Domain Name System
server)
The server that maintains a mapping of all host names and
IP addresses. Normally, this mapping is maintained by the
system administrator, but some servers support dynamic
mappings.
domain
A set of network resources in Windows NT and Windows
2000, such as users and groups of users. A domain may
also include multiple servers on the network. To gain access
to these network resources, the user logs into the domain.
domain name
The ASCII name that identifies the domain for a group of
computers within a network.
Ethernet
The most widely installed local area network technology.
10Base-T Ethernet provide transmission speeds of up to 10
Mbps. Fast Ethernet or 100Base-T provides transmission
speeds up to 100 Mbps and is typically used for LAN
backbone systems, supporting workstations with 10Base-T
cards. Gigabit Ethernet provides an even higher level of
backbone support at 1000 Mbps (one Gigabit or one billion
bits per second).
Ethernet address
The unique six-digit hexadecimal (0-9, A-F) number that
identifies the Ethernet interface.
Ethernet port
The port that houses the network card to provide Ethernet
access to the computer.
event
Any significant occurrence in the system that may require
notifying a system administrator or adding an entry to a log.
failover
A strategy that enables one Ethernet port to assume the role
of another port if the first port fails. If a port fails on a Snap
Server, the second port assumes its network identity (if the
two Ethernet cards have been configured for failover). When
the port comes back online, the original identities are
restored. Failover is possible only in a dual-Ethernet
configuration.
