In the Open Systems Interconnection (OSI) communications model, the application layer provides services for an application program to ensure that effective communication with another application progr [..]

  Seventh (top) layer in the OSI seven layer model. Layer Contains functions for particular applications services such as file transfer.

Layer 7 of the OSI reference model. This layer provides services to application processes (such as electronic mail, file transfer, and terminal emulation) that are outside of the OSI model. The application layer identifies and establishes the availability of intended communication partners (and the resources required to connect with them), synchron [..]

Layer seven of the OSI reference model. It serves as a means by which applications access communications services.

Internetworking Dictionary The top layer of the network protocol stack. The application layer is concerned with the semantics of work (e.g., formatting electronic mail messages). How to represent that data and how to reach the foreign node are issues for lower layers of the network. [Source: MALAMUD]

The application layer is a layer in the Open Systems Interconnection (OSI) seven-layer model and in the TCP/IP protocol suite. It consists of protocols that focus on process-to-process communication a [..]

<networking> The top layer of the OSI seven layer model. This layer handles issues like network transparency, resource allocation and problem partitioning. The application layer is concerned with the user's view of the network (e.g. formatting electronic mail messages). The presentation layer provides the application layer with a familia [..]

The Application Layer, the highest layer in the OSI protocol stack, contains the programs that invoke the services of the network to get useful work done. Some of these applications are written specifically for one network, while others are widely used standard applications. When these applications need to communicate with peers over the network, t [..]
