A 404 error is an HTTP status code that indicates the server could not find the requested webpage. When you attempt to access a webpage on a website, the server responds with various status codes to indicate the outcome of the request. The 404 error specifically signifies that the server could not locate the requested resource, typically because the URL is incorrect, the page has been moved or deleted, or there’s an issue with the server configuration.
In simpler terms, it’s like going to a library and asking for a book that doesn’t exist or has been misplaced. The librarian (server) checks their records and can’t find the book, so they tell you it’s not available. Similarly, when you encounter a 404 error on the web, it means the server couldn’t find the webpage you’re looking for.
Web browsers typically display a “404 Not Found” message to inform users that the requested page cannot be accessed. Website owners may customize the appearance of the 404 error page to provide helpful information or suggestions for navigation, such as links to the homepage or search functionality, to assist users in finding what they’re looking for despite encountering the error.
