3Com TokenLink VelocityTM XL PCI Network Interface Card Clean boot, Driver, Full-duplex, Ieee

2GLOSSARY

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 extension to the IEEE 802.5 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 software

A 3Com set of features that adds intelligence to NICs to optimize network performance and provide enhanced network management and control.

full-duplex

A mode of operation in which a token ring station can simultaneously transmit and receive independent data streams. Dedicated transmissions occur between the station and switch; token passing no longer occurs.

hexadecimal

A number system with a base of 16. In hexadecimal, the first 10 digits are 0–9 and the last six digits are A–F. This number system is identified in this guide by a number or character followed by “h.”

IEEE 802.5

The standard for the token ring access method and physical layer specifications developed by a subcommittee of the Institute for Electrical and Electronics Engineers (IEEE) 802 committee.
