without the IP part of layer 3, how can you send anything to an address, let alone all addresses?

this is for a report. I can give you a starting point.

When a packet is recieved by a hub, it broadcasts the packets through all active ports and the clients listening on the port will determine if the packet is destined to it, if not it will drop the packet.

When a packet is recieved by a switch it determines whether the layer 2 (MAC address) is contained within it's port or VLAN, if not, it goes to either a neighboring switch (if updated by a switch that hosts such advertising services) or directed to the default gateway (router). The switch, however, has no concept of layer 3 networking.

No, I have not answered your question but I hope this aids you in your research. However, I would look towards routers as that is the network layer device you are looking for.
