The given statement, "When an object is serialized, it is converted into a series of bytes that contain the object's data" is true.
Serialization is the process of converting an object into a format that can be easily stored or transmitted. When an object is serialized, it is transformed into a series of bytes, often in a specific format such as JSON, XML, or binary. This byte representation includes the object's data and sometimes its metadata.
Serialization is commonly used in programming to save the state of an object, facilitate data interchange between different platforms, or enable the transmission of objects over a network. Deserialization is the reverse process, reconstructing the object from the serialized bytes to restore its original state. Thus the statement is true.
