An Error 404 means that you have requested a page that does not exist. This is often caused because there's an error in the URL you typed or that the page you want has been moved (renamed). When you view a website with a browser, a program running on your computer (the browser) sends a request to the computer that hosts the website (the server) and asks for a specific page. The server processes the request, and if you've made a valid request it will send the text, pictures, etc. that make up the page back to your browser for display. If the request is not valid, the server will send back an error. Common errors are Error 404, meaning "Not Found," and Error 401, meaning "Unauthorized" because you are not signed in.
