Hence, irrespective of which software you use, it is the protocol which is considered at Application Layer used by that software. A user can use this protocol in either GUI based software like FileZilla or CuteFTP and the same user can use FTP in Command Line mode. HTTP is Application Layer protocol.Īnother example is File Transfer Protocol, which helps a user to transfer text based or binary files across the network. On the other hand, when we use a Web Browser, which is actually using Hyper Text Transfer Protocol (HTTP) to interact with the network. For example, designing software or text-editor cannot be considered as application layer programs. Free DVD player options are also available. except those applications which interact with the communication system. If you want to play DVDs in Windows 10, go to Microsoft Store to buy Windows DVD Player or another app that plays DVDs. Not every user application can be put into Application Layer. There’is an ambiguity in understanding Application Layer and its protocol. The transport layer does the rest with the help of all the layers below it. When an application layer protocol wants to communicate with its peer application layer protocol on remote host, it hands over the data or information to the Transport layer. Application layer takes the help of Transport and all layers below it to communicate or transfer its data to the remote host. Because this layer is on the top of the layer stack, it does not serve any other layers. Application layer is where the actual communication is initiated and reflects. This layer is for applications which are involved in communication system.Ī user may or may not directly interacts with the applications. This layer exists in both layered Models because of its significance, of interacting with user and user applications. Application layer is the top most layer in OSI and TCP/IP layered model.
