What operating system is considered to be stateless?

Chrome OS is considered a stateless operating system because it operates primarily from the cloud and focuses on providing a streamlined experience by using web applications. In a stateless system, the operating environment does not retain information about previous interactions or configurations once the session ends. This architecture is designed to enhance security, as it minimizes the persistence of user data and reduces the risk of malware or data corruption that could occur in a more traditional operating system setup that saves state locally.

In Chrome OS, user data and application settings are typically stored in the cloud, meaning that even if a device is reset or powered off, the user's data and preferences remain intact and accessible from any other Chrome OS device. This approach contrasts with other operating systems, which often rely on local storage and have a persistent state that can be modified over time, preserving configurations and files across sessions.
