GLOSSARY

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.)
