5-4-3 Rule

5 4 3 rule:-
5-4-3 rules mean that in your network you must have 5 segments of cables, with 4 repeaters, and that network must be 3 or less mixing segments. Its mean that if you have a network with coaxial cable’s network, then you must be 3 segments of 500m for 10Base5 and 185m for 10Base2 in your network with computers that will be connected with 2 repeaters. You can extend this type of network by installing 2 repeaters and 2 segment of 500m and 185m of cables.
If we talk about 10Base2 network in which we use BNC (British Novell Connector) with RG-58 cables, and Bus Topology, in this network we extend our network up to 925m and in 10Base5 network you can use up to 2500m, in this situation you can use only 5 segment of cables with 4 repeaters that connect these 5 cables with each other in a series and only 3 segments must be included computers and other devices. Half-meter is the minimum length of cable between computers, the BNC connector must be ended with terminator, you can put 30 computers on each segment, remember that the total length of all 5 segments must not be extended from 925m.
