The Application Layer of OSI Model
The application layer (Layer 7) is the topmost layer of the OSI model. It specifies the interfaces and supports services to the end users for network access.
The main functions of the application layer are as follows −
- It provides a virtual network terminal through which a user can log on to the remote host on the network.
- It provides facilities so that a user can access and retrieve files in a remote computer for local usage, as well as manage and store files on a remote computer from the local computer.
- It provides e-mail services.
- It helps to retrieve global information and services by providing access to distributed database resources.
