What does the Application Layer provide?

• A. Hardware addressing
• B. End-user network services
• C. Error detection
• D. Flow control

Answer: (B)

The main idea is that the Application Layer provides services directly to end-user applications. It defines how programs like web browsers, email clients, and file transfer tools access network resources and present data to users. This layer handles the protocols that support user-oriented tasks—such as HTTP for web pages, SMTP/IMAP for email, and FTP for file transfer—and it abstracts away the details of how data is actually transmitted across the network. In other words, it offers end-user network services and the interface applications use to communicate over the network. Lower layers handle hardware addressing, error detection, and flow control, so those functions aren’t the responsibility of the Application Layer.
