XDR: eXternal Data Representation

eXternal Data Representation(XDR) is a standard for the description and encoding of data. XDR is useful for transferring data between different computer architectures, and it has been used to communicate data between such diverse machines as the SUN WORKSTATION*, VAX*, IBM-PC*, and Cray*. XDR fits into the ISO presentation layer and is roughly analogous in purpose to X.409, ISO Abstract Syntax Notation. The major difference between these two is that XDR uses implicit typing, while X.409 uses explicit typing.
