Data Conversion: This is where the presentation layer performs bit order reversal functions, converts CR (byte code for a carriage return) to CR/LF, (byte code for a carriage return with a line feed) and converts integer numbers to floating point numbers. Whereas, protocol defines a standard set of guidelines under which the network operates, the network's architecture determines what protocol applies. This layer formats and encrypts data to be sent across a network, providing freedom from compatibility problems. » Java Functions of Presentation layer: Translation: The processes in two systems exchange the information in the form of character strings, numbers and so on. The presentation layer's basic function is to convert the data intended for or received from the application layer into another format. : Data Reformatting: When two computers exchange data, the data is changed to bit streams before it is transmitted. A successful data transfer technique is to adapt the data into a standard format before transmission. The Presentation Layer negotiates the Transfer Syntax.
