5-4-3 rule

5-4-3 rule applies to Ethernet running over coaxial cable. The rule states that a network can have a maximum of five cable segments with four repeaters, with three of those segments being populated. It is an “end-to-end rule, which means that it governs the number of segments, devices, and so forth, between any two nodes n a network. It is not a “total population” rule: you can have more than five cable segments, four repeaters, and three pupu8lated segment on an Ethernet network, but no more than those numbers between ay tow possible senders and receivers on that network.
