WebMar 14, 2024 · The Open Systems Interconnect (OSI) model is a conceptual framework that describes networking or telecommunications systems as seven layers, each with its own function. WebEthernet frame CRC (FCS) is usually understood to be on OSI layer 2, many people claim it is layer 1 on Ethernet, but that is incorrect (only preamble, SFD and IFG are layer 1 on Ethernet). I recommend a book called Computer Networks - A systems approach on this and many other subjects. It discusses CRC in-depth around page 92 through 102.

WebJan 25, 2024 · As previously mentioned the OSI model is a theoretical model. Though to answer your question, not all layers have headers. Layers 5 - 7 are typically just referred to as data. Layers 2 - 4 have headers. Layer 4 - Transport - TCP header. Layer 3 - Network - IP header. Layer 2 - Data Link - MAC header & FCS footer. WebChances are that if your payload got corrupt in transit, then Ethernet FCS is the first one to signal that. It is the most comprehensive, because it includes IP and TCP headers as well.
