ip

I know that this question sounds stupid, but over all these years, I still have difficulty explaining TCP/IP to people. I don't completely get it myself, and even after reading up on it, the distinction is not very clear. What I get so far is that IP deals with networks while TCP involves delivery of messages over that network. I'm not totally convinced though. Also, they reside on different layers of the Internet architecture. Could anyone disambiguate this distinction using a simple analogy or examples? Also, I read this somewhere

The difference is that TCP is responsible for the data delivery of a packet and IP is responsible for the logical addressing. In other words, IP obtains the address and TCP guarantees delivery of data to that address.

Is this correct? Thanks for helping me out. One last thing- Where does the ethernet come in all of this?
