Is Serialization like taking a picture of memory cells content?

By saving an object to a file and looking to binary data in that file, it seems like it is the same as the data in the heap.
can I say that data in this file is a copy of the binary data representing my objects and relationships between them in the memory?
to what extent am I right?

a dump of the heap. You can learn about the format

Serialization doesnot copy the object byte by byte from heap to file.Rather it copies enough information from the object that would be required to reconstruct the object again from the file.
