What is a 404 Error?

A 404 error, also known as ‘404 Page Not Found’, is an HTTP status code that indicates that the server was unable to find the requested resource. It doesn’t mean that the server itself isn’t reachable, but rather that the specific page you’re looking for doesn’t exist.

An error 404 code is an HTTP status code that indicates the server couldn’t find the requested webpage. When you click on a link or type a URL into your browser, the browser sends a request to the server hosting that webpage. If the server can’t find the requested page, it responds with a 404 page not found, letting you know that the page is not available.

Understanding HTTP Status Codes

To understand an error 404 code better, let’s take a quick look at HTTP status codes. These codes are provided by a server as a response to a request made by a client to the server. They provide information about the status of the request. The most common HTTP status codes are grouped into five categories:

  • 1xx Informational: Indicates that the request has been received and the process is ongoing.
  • 2xx Success: Signifies that the requested action has been received, understood, and acknowledged successfully.
  • 3xx Redirection: Indicates that additional steps are necessary to fulfill the request.
  • 4xx Client Error: Denotes that the request contains faulty syntax or cannot be fulfilled by the server.
  • 5xx Server Error: Indicates that the server encountered an issue preventing it from fulfilling a seemingly valid request.

As we can see, the 404 error code falls under the 4xx category, specifically indicating a client error.
