Serializable is a term used in computer science to describe the ability of an object to be converted into a format that can be easily stored or transmitted. This process allows the object's state to be saved, so it can be recreated later. Common formats for serialization include JSON, XML, and binary formats. In programming, making an object Serializable is essential for tasks like saving data to a file or sending it over a network. Many programming languages, such as Java and Python, provide built-in support for serialization, making it easier for developers to manage data efficiently.
