What is Serialization ? What are the Types of Serialization and their differences?

Serialization:
It is the process of converting an object to a form suitable for either making it persistent or tranportable.
Deserialization is the reverse of this and it converts the object from the serialized state to its original state.

Types:
1. Binary
2. XML

Differences:

Sno	Binary	XML
1	It preserves type fidelity , which is useful for preserving the state of the object between transportation and invocation.	It doesnt preserves type fidelity and hence state cant be maintained.
2	As it is the open standard its widely used	Not that much compared to Binary.
