Which of the following HTTP response codes indicates that the requested resource was not found?

Explanation:

The HTTP response code 404 indicates that the requested resource could not be found on the server. This status is commonly returned when a user attempts to access a webpage or resource that does not exist or has been moved without updating the corresponding link.

Common Causes:

• Incorrect URL entered by the user.
• Broken or outdated links pointing to resources that have been deleted or moved.
• Server misconfiguration or permissions issues preventing access to the resource.

How 404 is Represented:

When a 404 error occurs, most servers display a user-friendly error page with a message like "Page Not Found" or "The requested URL was not found on this server." These pages often include navigation options to help users find what they are looking for.

Best Practices for Handling 404 Errors:

• Custom Error Pages: Design a helpful error page that guides users to navigate back to the homepage or search for other content.
• Redirects: Implement URL redirects to direct users from outdated links to the correct location.
• Regular Link Maintenance: Periodically check and update links on your website to ensure they point to valid resources.
• Search Functionality: Provide a search bar on the error page to allow users to find related content.
