Is there a difference between a frame and a packet?
I am trying to understand the destination and source of communicating between two hosts.

packet layer 3 = layer 3 header
frame layer 2 = layer 2 header

So when you send a packet it sends both the packet and frame header?

Are there any specific rules to follow when trying to figure out the source and destinations?

between src and dst the layer 3 addresses remain the same, Layer 2 changes every hop
