L7

L7, or Layer 7, refers to the application layer in computer networking, which is responsible for managing how users and software communicate over the internet. It handles high-level services like web browsing, email, and streaming, translating data into formats humans can understand. Think of it as the layer where content and user interactions happen—everything from loading a webpage to sending a message. This layer enables applications to request services from the network, ensuring data is correctly formatted and delivered exactly where it needs to go.
