Error Code 404, also known as "404 Not Found," is a standard response code in web communications indicating that the server was unable to find the requested resource. It usually means that the web page the user is looking for could not be located on the server, but the server itself is reachable. This error often occurs when a webpage is deleted or moved without redirecting the old URL to a new one. A 404 error is a critical aspect of website maintenance and user experience, guiding webmasters to identify and fix missing pages.
