LOSSARY
3Com mode
A mode of operation for the 3Com TokenLink Velocity ISA
network interface card (NIC) that provides increased
throughput and expanded configuration options.
CAU
Controlled access unit.
Class of Service
A 3Com DynamicAccess feature that helps to optimize
network performance by letting you prioritize your
applications for efficient network access. High-priority
tokens are requested when the network transmits data
for selected applications.
Clean boot
A DOS boot with no memory managers or other
programs (such as drivers) loaded in memory.
DAU
Dual access unit.
Driver
A program, usually resident in the server or workstation
memory, that controls the network hardware (such as
NICs or controllers) or implements the protocol stacks
through which higher-level applications communicate
with the network hardware.
DTR
Dedicated Token Ring (DTR). An IEEE standard that
increases network performance in switched token ring
environments. It allows data transmission using dedicated
resources between the station and the concentrator.
Transmissions can be either half-duplex or full-duplex.
DynamicAccess technology
A 3Com set of features that optimize network
performance. (
