SMC 5-4-3 Rule
Between any two PCs or other stations in the same 10 Mbps collision
domain, there may be:
•
•
•
* The remaining two segments are unpopulated; these are known as
inter-repeater links or IRLs. This distinction between populated and
unpopulated segments is significant for coax networks only.
