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. 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. textron tributes workstride https://jocatling.com
