<FONT color=#1a1973>> A switch does not necesarily have to provide dual-speed or auto-sense</FONT>
<FONT color=#1a1973>> capabilities, although very many of them do. Also note that dual-speed</FONT>
<FONT color=#1a1973>> hubs must buffer input from a 100baseT to a 10baseT NIC. When that buffer</FONT>

<FONT color=#1a1973>> therefore will always be limited by the slower NIC.</FONT>
