Serialization is the process of converting an object into a
stream of bytes. Deserialization is the opposite process of
creating an object from a stream of bytes.
Serialization/Deserialization is mostly used to transport
objects (e.g. during remoting), or to persist objects (e.g.
to a file or database).Serialization can be defined as the
process of storing the state of an object to a storage
medium. During this process, the public and private fields
of the object and the name of the class, including the
assembly containing the class, are converted to a stream of
bytes, which is then written to a data stream. When the
object is subsequently deserialized, an exact clone of the
original object is created. 
?	Binary serialization preserves type fidelity, which is
useful for preserving the state of an object between
different invocations of an application. For example, you
can share an object between different applications by
serializing it to the clipboard. You can serialize an object
to a stream, disk, memory, over the network, and so forth.
Remoting uses serialization to pass objects "by value" from
one computer or application domain to another. 
?	XML serialization serializes only public properties and
fields and does not preserve type fidelity. This is useful
when you want to provide or consume data without restricting
the application that uses the data. Because XML is an open
standard, it is an attractive choice for sharing data across
the Web. SOAP is an open standard, which makes it an
attractive choice. 
There are two separate mechanisms provided by the .NET class
library - XmlSerializer and SoapFormatter/BinaryFormatter.
Microsoft uses XmlSerializer for Web Services, and uses
SoapFormatter/BinaryFormatter for remoting. Both are
available for use in your own code.

serialization is process of convert object into stream of 
bytes.
2 types of serialization
1. binary serialization
2. XML serialization

serialization is the process of converting an object into a 
sequence of bits so that it can be stored on a storage 
medium (such as a file, or a memory buffer) or transmitted 
across a network connection link. When the resulting series 
of bits is reread according to the serialization format, it 
can be used to create a semantically identical clone of the 
original object. For many complex objects, such as those 
that make extensive use of references this process is not 
straightforward.
Serialization is a mechanism by which you can save the 
state of an object by converting it to a byte stream.
Two types:
1.Binary Serializable
2.XML Serializable
Methods:
	The serializable interface is an empty interface, 
it does not contain any methods. So we do not implement any 
methods.
Use:
	Whenever an object is to be sent over the network, 
objects need to be serialized. Moreover if the state of an 
object is to be saved, objects need to be serilazed.
Externalizable:
	Externalizable is an interface which contains two 
methods readExternal and writeExternal. These methods give 
you a control over the serialization mechanism. Thus if 
your class implements this interface, you can customize the 
serialization process by implementing these methods.
