broadcast domains and collision domains
collision domains
a historical footnote
its difficult to find a collision these days
the word "collision" is misleading
the network was one big segment
only one station can talk at a time
is the line clear? ok i can talk
carrier sense multiple access CSMA
when two people spoke at the same time there was a collision
collision detection CD
send the jam signal
broadcast domains
spread the word
everyone must know
arp request
operating system notifications
some dynamic routing protocols
how far can a broadcast go
passed by a switch/bridge
stops at the router
this can be important
more devices, more broadcast
