No more that 5 cable segments can be used between two nodes (don't let it pass through more than 4 devices defore it gets to destination)

Any two nodes cannot be connected through more than 4 devices (Switches, routers, etc)

If you're using coaxial cable (who does anymore?) no more than three segments can have devices attached to them.

 

Should have added that if you're using fibre optic cabling throughout the network then the 5-4-3 rule doesn't apply at all.

 

and also when bridges are involved. They can isolate domains from each other.

 

I find it helpful to actually draw diagrams of these sorts of things. I can't really understand it when I just read text but a good graphic makes all the difference.

 

You mean something like this ?

Google is your friend!

 

Touche', Simon.

 

right

5 segments connected with
4 repeaters with
3 segments max having hosts on them, therefore
2 segments with no hosts and
1 collision domain!

remember, this rule is for co-ax or tp cable in half duplex mode. In other words, it don't apply to switched networks
