<p>Ethernet is one type of local area network (LAN) topology that is supported
|
||
|
|
by the operating system. i5/OS™ Ethernet provides support for the Digital
|
||
|
|
Equipment Corporation, Intel™ Corporation, and Xerox standard (Ethernet Version 2) and the IEEE
|
||
|
|
802.3 standard.</p>

<dt class="bold">Half-duplex Ethernet</dt>
|
||
|
|
<dd>Generally, multiple stations in an Ethernet network show a single data
|
||
|
|
path. Therefore, only one station may transmit data at a time. This is called
|
||
|
|
half-duplex Ethernet. The station may transmit only or receive only, but not
|
||
|
|
both simultaneously.
|
||
|
|
</dd>
|
||
|
|
<dt class="bold">Full-duplex Ethernet</dt>
|
||
|
|
<dd>Full-duplex Ethernet enables stations to simultaneously send and receive
|
||
|
|
data on the network, eliminating collisions. This is accomplished through
|
||
|
|
the use of a full-duplex LAN switch. Ethernet switching splits a large Ethernet
|
||
|
|
into smaller segments. Full-duplex Ethernet requires the following:
|
||
|
|
<ul>
|
||
|
|
<li>Twisted-pair cable transmission medium</li>
|
||
|
|
<li>Ethernet network interface cards</li>
|
||
|
|
<li>A full-duplex LAN switch</li></ul>Full-duplex 10 Mbps Ethernet has simultaneous 10 Mbps receiving and
|
||
|
|
10 Mbps sending paths.
|
||
|
|
</dd>
|
||
|
|
<dt class="bold">Fast Ethernet</dt>
|
||
|
|
<dd>Fast Ethernet standard (IEEE 802.3U) increases Ethernet by operating
|
||
|
|
speeds from 10 Mbps to 100, half or full duplex. The iSeries™ Ethernet
|
||
|
|
adapters support 100BASE-TX network devices that use category 5 shielded and
|
||
|
|
unshielded twisted-pair (STP, UTP) cable.
