Which OSI Layer provides an interface between the network protocol stack and networked services such as file & print services, database services, messaging services, and web services?

Application

Data Link

Network

Physical

Presentation

Session

Transport

The correct answer to the following question will be Option A (Application).

Explanation:

In the OSI model and even in the TCP/IP protocol package, the application layer is a layer. Consists of protocols concentrating on system-to-process interaction throughout an IP network and providing a firm interface for correspondence and end-user facilities. This application Layer provides user connectivity to the network, whether human or machine. This offers applications and interfaces support such as e-mail, shared data management, and other centralized technical services.

Therefore, Option A is the right answer.
