A 404, often referred to as a “404 error” or “HTTP 404,” is a standard response code in web communications indicating that the client was able to communicate with the server, but the server could not find what was requested. This error message is a part of the HTTP (Hypertext Transfer Protocol) standard response codes. When you encounter a 404 error, it means the webpage you were trying to reach could not be found on the server. This is typically due to one of the following reasons:

  1. The URL or its content (such as files or images) was either deleted or moved without adjusting any internal links accordingly.
  2. The URL was typed incorrectly or the link that was clicked on points to the wrong URL.
  3. The server responsible for the website is not running or the connection is broken.

The 404 error message can appear in just about any way imaginable depending on what website it’s shown from. Web designers often customize the default 404 error page to be more helpful to the user, sometimes including a search function or a link back to the website’s home page.

In terms of user experience, encountering a 404 error can be frustrating, but it’s a common part of navigating the web. Website administrators aim to minimize these errors by regularly checking their sites for broken links and using tools to monitor the health of their websites.
