I've seen the term "serialized" all over, but never explained. Please explain what that means.

Serialization is the conversion of an object to a series of bytes, so that the object can be easily saved to persistent storage or streamed across a communication link. The byte stream can then be deserialized - converted into a replica of the original object.
Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization.
What happens if you try to send non-serialized Object over network? When traversing a graph, an object may be encountered that does not support the Serializable interface. In this case the NotSerializableException will be thrown and will identify the class of the non-serializable object.
You can determine whether an object is serializable at run time by retrieving the value of the IsSerializable property of a Type object that represents that object's type.
Serialization usually refers to the process of converting an abstract datatype to a stream of bytes (You sometimes serialize to text, XML or CSV or other formats as well. The important thing is that it is a simple format that can be read/written without understanding the abstract objects that the data represents). When saving data to a file, or transmitting over a network, you can't just store a MyClass object, you're only able to store bytes. So you need to take all the data necessary to reconstruct your object, and turn that into a sequence of bytes that can be written to the destination device, and at some later point read back and deserialized, reconstructing your object.
