sorry i cant copy it here.. i'll try n explain 3 switches each has 2 comuters conected to them and those (3 seperate LAN s) 3 swithes a gain connet to another switch (bridge)with 3 connections
and the bridge connects to a router... does it make any sense

this is wht the book says

" do you see the nine collision domains? Just in case
that’s a no, I’ll explain. The all-hub network is one collision domain; the bridge network
equals three collision domains. Add in the switch network of five collision domains—one for
each switch port—and you’ve got a total of nine"

whr did he gt the five collision domains??

whr did he gt the five collision domains??

It should be nine collision domains like he explained not 5 right? Switches are full duplex so sending/receiving traffic does not have an opportunity to collide, thus making it one collision domain per switch\PC connection
