<br><br>ARGH, lost power right before I was ready to hit Post... now I have to start over hehehe.<br><br>- gigabit networking is 1000mbps<br>- a device that supports 10/100/1000, will allow any device that supports either 10, 100, or 1000 mbps to connect (assuming ethernet, and proper cable types)<br>- a device that supports 1000mbps does NOT have to support 10mbps or 100mbps<br><br>As you can see, 10/100/1000 means that gigabit networking is supported, but the converse does not necessarily apply. A gigabit device does NOT have to support 10 or 100mbps.<br><br>Granted, most of the gigabit devices that you will run across will be 10/100/1000; but you should be aware that gigabit does not mean 10mbs or 100mbps (10BaseT or 100BaseTX (I am usually lazy and just put 100BaseT)).<br><br>Normally, gigabit only devices came out when gigabit network first came out, or are for high end equipment only. <br><br>As an example, 3com has a modular switch(es), that has gigabit modules that only support 1000mbps.<br><br>http://www.3com.com/products/en_US/detail.jsp?tab=prodspec&sku=3C16817-US&pathtype=purchase<br><br>3Com® Switch 4007R Layer 2 Gigabit Ethernet Starter Kit<br><blockquote class="ip-ubbcode-quote">

<br><br>Notice how on this bundle, they specify 10/100Base-TX and gigabit ethernet.<br><br>Edit: Ooops... I forgot to cut/paste the link to the second 3com switch bundle... and I closed out that window already. If you want to read more, just go to a "major" networking vendor (3com, Bay Networks, Cisco, etc)
