What is serialization?

Hi Guys,
This may sound stupid but I want to know what is a serialized class and whats the different between a serialized class and any other Class?
Hope someone can answer this question
hy,
Serialization is the process of saving the state of an object by converting it to a stream of bytes. The object can then be persisted to file, database, or even memory. The reverse process of serialization is known as deserialization.
