What is Layer Eight?
1.
In networking, the OSI model refers to the seven layers of the network stack. This model is sometimes extended to eight layers in order to incorporate the user. This is often used in jokes meant to insult a user by implying operator error.
User: What's wrong with my Internet connection?
Tech: Looks like a layer eight issue.
User: Is that bad?
Tech: Depends. You didn't pay your bill.
