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. (See also Class of Service.)
