Layer 8
The OSI (Open Systems Interconnection) networking model contains seven layers describing the architecture for data communications between computers connected via a network. While not an official layer of the OSI model, layer 8 is sometimes called the"user" layer or "political" layer. Layer 8 is considered humorous in the world of networking professionals.
When there is an issue at the user end, some call it a layer 8 issue. This term is similar to other humorous user-related "errors," like the PEBKAC (problem exists between keyboard and chair) error or the ID-10-T error. Referring to layer 8 as the "political" layer is because some people say that understanding the OSI model requires understanding layer 8. Network neutrality, spectrum management, and digital inclusion are considered political policies and help to shape the 7-layer OSI model.
