The document discusses the 7 layers of the OSI model for networking. It describes that there are 7 layers total, with headers and trailers added to data as it passes through each layer from the application layer down to the physical layer. Specifically, headers are added at layers 6 through 3, while trailers are typically added at the data link layer. Each layer has a distinct purpose in the transmission of data across a network.
