External Data Representation


External Data Representation - Definition

eXternal Data Representation (XDR) is an implementation of the presentation layer in the OSI model. XDR allows data to be wrapped in an architecture independent matter so data can be transferred between heterogenous computer systems. Converting from the local representation to XDR is called encoding. Converting from XDR to the local representation is called decoding. XDR is implemented as a software library of functions that is portable between different operating systems and is also independent of the transport layer. Sun RPC uses XDR.

XDR defines the following data types:

boolean
char
short
int
