What is object marshalling?

Converting an object in memory into a format that can be written to disk, or sent over the wire, etc.

Wikipedia's description.

I beg to differ, Wikipedia is pretty clear on this.

In computer science, marshalling (similar to serialization) is the process of transforming the memory representation of an object to a data format suitable for storage or transmission. It is typically used when data must be moved between different parts of a computer program or from one program to another.
