Definition
A 404 error is an HTTP status code that indicates that the server could not find the requested resource. This typically occurs when a user tries to access a webpage that either does not exist, has been moved, or has been deleted.
Function
The main function of the 404 error is to inform users that the specific page they are trying to access is unavailable. It serves to improve user experience by providing feedback, rather than displaying a blank page. A well-designed 404 error page can guide users back to functional areas of the website, offer search options, or suggest similar content, thus helping to keep them engaged with the site.
