Full-Duplex Mode: A mode of

media utilization whereby data

can ﬂow in both directions

simultaneously acrossthemultiple

wire pairs of a physical link. While

full-duplex operation is not deﬁned

per se in the IEEE 802.3u-1995

speciﬁcation, the speciﬁcation does

deﬁne a mechanism for this mode

to be autonegotiated between

devices on each end of a link.

Full-duplex mode is typically

found on switches. The HP-PB

10/100Base-TX card supports both

full- and half-duplex

communications.

Half-Duplex Mode: The media

utilization mode of IEEE

802.3u-1995 networks whereby

data can ﬂow in only one direction

at a time across the multiple wire

pairs of a physical link.

Hardware Path: An identiﬁer

assigned by the system according

to the physical location (slot) of the

card in the hardware backplane.

On Series 800 systems, the I/O

subsystem identiﬁes each LAN

card by its hardware path.

Hostname: Name of system on

the network. Refer to the network

map in appendix B for example

usage.

Hub: A network interconnection

device that allows multiple devices

to share a single logical link

segment. Hubs are generally

either 10 Mbit/s or 100 Mbit/s

devices. Use either a 10Base-T or

100Base-TX hub with the HP-PB

10/100Base-TX card.

IEEE: The Institute of Electrical

and Electronics Engineers. A

national association, whose

activities include publishing

standards applicable to various

electronic technologies. The IEEE

technical committees are

numbered and grouped by area.

For example, the 800 committees

study local area network

technologies. The 802.3 committee

produced the standard for a

CSMA/CD local area network,

which has been adopted by ANSI.

IEEE 802.3u-1995 network: A

10 or 100 megabit-per-second LAN,

speciﬁed in the IEEE 802.3u-1995

Standard for Local Area Networks.

It uses the Carrier Sense Multiple

Access/Collision Detection

(CSMA/CD) network access

method to give every node equal

access to the network.

Internet Address: The network

address of a computer node. This

address identiﬁes both which
