The OSI model for networking contains 7 layers to describe the architecture for data communications between computers connected via a network. While not an official layer of the OSI model, layer 8 is sometimes referred to as 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 error or the ID-Ten-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.
