Description: The term ‘NotFound’ refers to an error message indicating that a specific value was not found during a search in a computer system. This message is commonly associated with the HTTP status code 404, which is used on the web to signal that a requested resource is not available on the server. In a broader context, ‘NotFound’ can apply to various situations in programming and databases, where an element is searched for but does not exist in the collection or dataset. This type of error is crucial for debugging and exception handling, as it allows developers to identify issues in search logic or data availability. Clear communication of this error is essential for enhancing user experience, as a clear message can guide the user towards the correct action, such as checking the URL or trying another search. In summary, ‘NotFound’ is an essential indicator in error handling that helps maintain the integrity and functionality of applications and computer systems.
