Dedicated to Fault-Tolerance
Glossary-4
Dedicated
Assigned to one purpose or function.
Device (network)
Any discrete electronic item connected to a network which either
transmits and receives information through it, facilitates that
transmission and reception, or monitors the operation of the network
directly.
DLM
Distributed LAN Monitor. DLM is a feature of some SNMP management
devices which allows that device to locally monitor other devices under
its control and report to a central network management station any noted
errors. This frees the network management station from directly
monitoring every SNMP device.
DNI
Desktop Network Interface. DNI cards are devices which are added to
workstations to provide them with a connection to a network (NIC).
Dual Attached
Connected to an FDDI dual counter-rotating ring through the use of A/B
ports
.
Dual Homing
A station connection method for FDDI which connects a device’s A/B
ports
to the M ports of two separate dual-attached concentrator devices,
providing fault-tolerance.
EEPROM
Electronic Erasable Programmable Read-Only Memory.
Encryption
A security process which encodes raw data into a form that cannot be
utilized or read without decryption.
EPIM
Ethernet Port Interface Module. EPIMs are added to
specifically-designed slots in Cabletron Systems Ethernet products to
provide connections to external media. EPIMs allow a great flexibility in
the media used to connect to networks.
Ethernet
A networking technology which allows any station on the network to
transmit at any time, provided it has checked the network for existing
traffic, waited for the network to be free, and checked to ensure the
transmission did not suffer a collision with another transmission. See also
CSMA/CD
.
Fast Ethernet
A networking technology based on the Ethernet technology. Fast
Ethernet operates at 10 Mbps, ten times the speed of standard Ethernet
networks.
Fault-Tolerance
The ability of a design (device or network) to operate at full or reduced
capacity after suffering a failure of some essential component or
connection. See also redundant.
