What term describes the storage of webpage interaction data on a local computer?

The term that describes the storage of webpage interaction data on a local computer is local storage. Local storage allows web applications to store data directly in a user's browser, enabling them to maintain state and remember user preferences even after the browser is closed. This storage mechanism is typically retained per origin and is accessible through web APIs, making it an efficient way to handle data locally without the need for server interaction.

In this context, local storage is valuable because it provides a simple and user-friendly way for applications to save and retrieve data, enhancing user experience by allowing for faster access to frequently used information and maintaining session state. This contrasts with other options such as remote storage, which implies storing data on a remote server and typically requires internet access, or cloud storage, which involves offloading data to managed services in the cloud. A data warehouse, on the other hand, refers to a centralized repository for structured and unstructured data used for reporting and analysis, which is quite different from the local storage concept.
