Hub physical layer

WebInstead of switches, vendors created LAN hubs. The LAN hub provided a number of RJ-45 ports as a place to connect links to PCs, just like a LAN switch, but it used different rules for forwarding data. LAN hubs forward data using physical layer standards, and are therefore considered to be Layer 1 devices. WebPhysical Layer) ist die unterste Schicht.
