Network layers

The seven Open Systems Interconnection (OSI) layers are:

Layer 7: The application layer

This is the layer at which communication partners are identified -- Is there someone to talk to? -- network capacity is assessed -- Will the network let me talk to them right now? -- and where the data or application is presented in a visual form the user can understand. This layer is not the application itself, it is the set of services an application should be able to make use of directly, although some applications may perform application-layer functions.

Layer 6: The presentation layer
