Presentation Layer


Presentation Layer is a Communication Layer


Presentation Layer of the OSI-Model is responsible for the delivery and formatting of information to the Application Layer for further processing or display.

Presentation Layer relieves the Application Layer of concern regarding syntactical differences in data representation within the end-user systems.

An example of a presentation service would be the conversion of an EBCDIC-coded text computer file to an ASCII-coded file.

Encoding, Decoding, Encryption and Decryption is typically (within the OSI-Model) performed at the Presentation Layer or within lower levels.
