What does it mean to 'serialize' data?

The concept of serialization refers to the process of converting data structures or object states into a format that can be easily stored or transmitted and reconstructed later. This is fundamental in various programming and data storage contexts, as it allows complex data types, such as objects, to be converted into a linear format that can be saved to files, databases, or sent over networks.

When data is serialized, it can be represented in formats like JSON, XML, or binary, ensuring that it retains its structure and information integrity when it is stored or transferred. The ability to convert data into a storable format allows for efficient storage and facilitates processes like data interchange between different systems or applications.

While encryption, formatting for user display, and data transfer are important concepts in computing, they do not align with the core definition of serialization, as those processes serve different purposes within data handling and management.
