comment How does communication between 2 computers in a single network happen?
Thanks a lot! How would the ARP part have changed if I were pinging google.com? When I use Google's IP address, what exactly sends my packet to the nearest router to me? Here ARP wouldn't be useful, since knowing the physical address of Google's computer is useless to me. It will be needed by the last router that sends it to Google. But to my computer it is useless. Also, I don't have a routing table in my computer. How then does such a packet go to the nearest router automatically?

Yes, but question is how will my computer eventually find my friend's NIC address? My only knowledge of logical address -> physical address mapping is that of ARP, which doesn't seem to apply here.

@Ramhound, I'm sorry about that. Forouzan is the author of a popular networking book. By physical address, I meant the NIC address. Yes, I knew what IP stands for. No confusion there :)

@techie007, would you please tell me why the question is broad? I speak of a specific scenario of using the ping command in a very basic network setup. I should have mentioned that it is an IP-based network, but I thought the mention of IP-address meant that. It would be great if you could help me identify what is ambiguous about my question :)

@Ramhound, Okay, I didn't know physical addresses are re-assignable. My knowledge of them being fixed was straight off "Forouzan". But in the example I quote, we don't set physical addresses that. Anyway, whatever the physical address is, how will my computer find that out?

@techie007, can you please tell me what host-based is? I just know that host is the opposite of a client (a server). But I haven't really encountered that phrase (nor could I search it on the web).

@Ramhound, What do you mean by : "his physical address is the ip address he assigned it.". Physical addresses are fixed and imprinted on the computers.

Downvoter, care to explain? I'm willing to explain anything here. I have done my reading, but still have these questions.
