Uni - Multi - Broad Casting
Uni
Single Destination
One Sender One Receiver
Mac Address required
Most common transmission
Broadcast
Broadcast by 12 hexadecimals or 48 binary code
Every device must receive broadcast traffic
FF-FF-FF-FF-FF-FF = all
Addressing through IP Addressing as well
Broadcast frame asking who is the computer they are looking for . Then unicast back the response
Broadcast Storm
Repeating through the network = Loop
Loops are created NIC trapped into a loop
It will crash the network
Spanning tree protocol kills the loops in the network while allowing redundancy (Hubs crash networks, Use Switches)
Plugging 2 cables into a hub you just created your own spam loop
Broadcast doman
Logical group
Cannot leave the broadcast domain
Routers are the border police of broadcast domains
Routers run seprate broadcast domains
Routers act as a boarder ensuring the spam stop
Multi
One or multiple receivers
Uses address range
Same transmission group
Break to individual Ethernet multicast address
Address can be sent out like a zoom or radio channel by the mac address
VLAN
Switches can separate BC domains with VLANs
