Which is a role of the application layer?
The application layer includes protocols specific to network applications such as email, file transfer, and reading data registers in a PLC. It is responsible for providing network services directly to end-users or applications, encompassing protocols like SMTP for email, FTP for file transfer, and other application-specific protocols.
Amswer IS A
The Application Layer (Layer 7 of the OSI model) provides network services directly to end-user applications. Its role includes handling protocols that enable specific network applications. The Application Layer specifies how these applications interact with the network to send and receive data.

A. Includes protocols specific to network applications such as email, file transfer, and reading data registers in a PLC The Application layer in the OSI model includes protocols that are specific to network applications, such as email (e.g., SMTP), file transfer (e.g., FTP), and protocols used for communication with devices like Programmable Logic Controllers (PLCs). It is responsible for providing network services directly to end-users or applications.

answer = A
the answer is A. Protocols specific to network applications such as email, file transfer, reading data registers in a PLC
actual user applications are above application layer.
A is correct. The primary role of the application layer, the top layer in the OSI model, is to provide network services to user applications, enabling them to communicate and interact with each other and with network resources. It implements protocols that define how applications communicate, such as HTTP for web browsing, SMTP for email, and FTP for file transfer.
