What is the role of data serialization process in programming?

Serialization is the process of converting a data structure or object into a format that can be saved or transmitted (for example, to a file or over a network). In programming, serialization allows:

• Saving the state of objects for later restoration (deserialization).
• Transmitting data between different components or systems, often with different programming languages.

For example, in Python, the pickle module is often used for serialization:

import pickle

# Object to serialize
data = {'name': 'Ivan', 'age': 30}

# Serialization to bytes
serialized_data = pickle.dumps(data)

# Deserialization back to object
restored_data = pickle.loads(serialized_data)

print(restored_data)  # {'name': 'Ivan', 'age': 30}

Thus, serialization facilitates storing and exchanging data between different parts of an application or between different systems.
