OSI Ethernet/802.3的物理层 集线器 多个主机 主机 10Base2—细缆以太网 10Base5—粗缆以太网 10BaseT—双绞线 Emphasize: Network topology is not necessarily connected to network technology. For example, many Ethernet networks have a backbone bus topology. However, adding a switch or a hub to an Ethernet network changes it to a star topology. IEEE 802.3u defines the standard for a CSMA/CD LAN operating at 100Mbps, Fast Ethernet. In the case of Ethernet, such as 10BaseT, the first part describes the speed of the cable, the second part describes whether it is baseband or broadband cable, the final part describes the media. So, 10BaseT is 10 Mbps baseband twisted-pair cable.
