1-3Getting StartedFast EthernetFast Ethernet is a networking standard defined by the Institute ofElectrical and Electronic Engineers (IEEE) in the IEEE 802.3uSpecification. Fast Ethernet runs at 100 Mbps, or at 200 Mbps in FullDuplex mode.Fast Ethernet uses the same Carrier Sense Multiple Access withCollision Detection (CSMA/CD) architecture used on 10BASE-Tand 10BASE-2 10 Mbps network specifications, which allows foreasy integration with existing networks.Adaptec DuraLAN NICsNote: 64-bit NICs will also work in 32-bit PCI slots.Adaptec provides the following PCI 10/100 DuraLAN Fast EthernetNIC models:n ANA-69011/ TX Single32™—a single-port 32-bit NIC supportingautosensing between 10 and 100-Mbps line speeds.Figure 1-1.
