Layer 6 – The Presentation Layer

     Layer 6, the presentation layer, is responsible for how an application formats the data to be sent out onto the network. The presentation layer basically allows an application to read (or understand) the message.

     Examples of presentation layer functionality include:

          • Encryption and decryption of a message for security

          • Compression and expansion of a message so that it travels efficiently

          • Graphics formatting

          • Content translation

          • System-specific translation
