Term: 404 Error
404 Error (Wikipedia)
In computer network communications, the HTTP 404, 404 not found, 404, 404 error, page not found, or file not found error message is a hypertext transfer protocol (HTTP) standard response code, to indicate that the browser was able to communicate with a given server, but the server could not find what was requested. The error may also be used when a server does not wish to disclose whether it has the requested information.
The website hosting server will typically generate a "404 Not Found" web page when a user attempts to follow a broken or dead link; hence the 404 error is one of the most recognizable errors encountered on the World Wide Web.
Definition of "404 Error" by Sutherland Shire Web Design: A "404 Error" is a standard HTTP status code that indicates the server could not find the requested webpage. This error occurs when a user tries to access a URL that does not exist on the server. The server responds with a 404 status code to inform the user that the requested resource is not available.
