  1. Not if you ask the right people. You should. This thread is worthless.
  2. Just because you don't have an IP address configured on the nodes doesn't mean you don't have the TCP/IP protocol stack enabled. Moderator, please delete thread.
  3. I imagine that most every question on this site can ultimately just be tested by the OP. Do me a favor and delete this thread. Thank you.
  4. Let me rephrase my question: If I have a LAN with neither a static nor a DHCP configured IP address assigned to the nodes within the LAN, will I be able to communicate from one computer to the next. If not, why not, and what will I need to be able to do so? thanks
  5. Hi, I understand the OSI model pretty well, as you're right, it is the most fundamental of all topics in any networking course. But despite much reading, I don't have it all down as I'd like, hence, the questions, and judging from some of the diversionary responses here, have come to believe that some others don't have it down as well as they should either. This question, which probably could have been answered in a clear, concise sentence or two, has been pestering me for a while. It seems like I once read or heard something by Meyers where he said that a computer doesn't even need an ip address for communication unless it's connecting to an outside network, but I don't remember for sure if or where I read that. And I'm aware of the similarities of LANs and WANs, and that mac resolution takes place on the latter, from one router to the next, however, within a LAN, it seems to me that there's no reason for the logical IP addressing scheme, when all the physical mac addresses are known by the switch, and could therefore transfer data from one computer to the next without any need for an ip address. But since I may be wrong, I ask questions.
  6. My key words are "Is there any reason for a computer to have an ip address if it will only be communicating within a LAN with no internet access?", not "how does TCP/IP work with arp?" The latter question was in response to a previous response made by someone at least trying to be helpful. He said IP is L2 agnostic, which makes it seem like TCP/IP is not involved in L2 processing, something I desire clarity on because he then basically said that TCP/IP or some other protocol would be necessary for theoretical mac address only communication within a LAN, which would effectively negate the need for IP addressing within that LAN, which is a point directly pertaining to my original question. If you don't know the answer, please don't feel the need to respond. Or, if you know where a direct answer to my question can be found, please provide the link, or the page number of the book, so I can go check it out in the library. Thanks
  7. I have already spent many hours reading books in my networking studies, however, I've been unable to find a direct answer to my question anywhere I've searched. That's why I'm asking the question here. What's wrong with asking my question in an internet forum---especially one dedicated to IT. Is that not primarily what such forums are for? If you don't know the answer, then you don't have to answer it. I guess I'll try Daniweb. Can anyone recommend any other internet forums where I can acquire helpful answers to my questions, or am I going to just be told to google that too. Thanks
  8. Please find them for me then and post them here, unless it would be easier to just answer the questions. Thanks
  9. Then how does TCP/IP work in conjunction with arp once the data has reached the LAN?
  10. So, TCP/IP is not capable of routing data amongst different MAC addresses in a LAN?
  11. Wouldn't the computers be able to communicate with each other via mac addresses?
  12. Is there any reason for a computer to have an ip address if it will only be communicating within a LAN with no internet access? thanks
