Syntax conversion, Computer Network Security

Write down the significance of the syntax conversion . Syntax Conversion is described below:

Syntax conversion is a significant function carried out in the presentation layer. It is generally a process of converting the syntax of data received from higher layer that is application layer into a standard format which can be easily understood by all the receiving layers. The benefit of performing syntax conversion is that it enables a smooth data communication among different OSI layers. (Which contain their own syntax). While the conversion of syntax is being done, presentation layer ensures the semantics of messages remain unchanged.

Let us take an example wherein two systems (which follow two different syntax) are communicating with each other, one system stores data in big-endian representation  and the other stores data in small endian representation.

In order to arrange the communication between these two systems the best method is to convert data into a “universal” format that is understood by both the systems. The advantage of using such data conversion approach is that it is extensible that is whenever a new system with different data format is added then instead of understanding different format  used  by  the  other  systems  the  newly  added  system  required  to  understand  the  way  of converting data to and then from the universal format.
