Hello Forum,
If a certain information content (for ex. a word document) is sent by a computer in a home network (small LAN) ,over the internet, to another computer in a different geographical location, I believe the TCP/IP protocol suite takes care of the document transmission over the internet, i.e. it breaks the document down into packets and attaches to each packet all the needed information (sender, receiver, error correction, etc.)
Where does the ethernet protocol fit in this scenario? Is ethernet a different layer protocol used only for small LANS? In a small home network, the connected machines still get assigned IP addresses (which sounds like TCP/IP being used). I know ethernet is also based on packets. Does the IP protocol overlap the ethernet packets once the packets leave the LAN to move through the Internet?
IP packets can be of different size up to a maximum size. If a document gets broken down into IP packets for transmission over the Internet, will those packets have all the same size equal to the maximum size? What if the document is first subdivided into ethernet packets? Do those packets get converted into IP packets later?
thanks,
