HUB:
Sends packets to all connected nodes-has no intelligence.
Advantages:
Very cheap
No set up
Disadvantages:
Very inefficient
Many collisions
Generates lots of redundant traffic

Switch:
Packet inspection (when a packet is received at the switch it will look at the address and send it to the right destination)
LAN connection devices
Advantages:
Very few collisions
Increased performance/efficiency
packet inspection
Disadvantages:
Can be hard to set up

Routers:
Internet connectivity Device
connects networks on the internet
Connects networks to the internet
Advantages:
Routers broadcast connectivity information to each other
Can automatically find alternate paths through a network
selects the best path for each packet based on its knowledge of the network
