In a computer network, what is the main function of the application layer?

To provide network services to the applications
To transmit data between network devices
To package data for transfer
To route data between networks

Correct Answer: A. To provide network services to the applications

Detailed Explanation

The main function of the Application Layer (Layer 7 of the OSI model) is to provide network services to the applications that users interact with, such as web browsers, email clients, and file transfer tools.

This layer allows software programs to use the network by providing services like HTTP, FTP, SMTP, and DNS. It helps users send emails, browse websites, download files, and more — all by using the network behind the scenes. Without the application layer, users wouldn’t be able to access or use network-based applications easily.
