It is a server error code which is returned by the server what a particular webpage or the file is missing from the webhost server. Any one have another idea about it??

404 is a error page where for a link there is no web page.

You rightly described it. No need to ask to anyone else.

The 404 or Not Found error message is a HTTP standard response code indicating that the client was able to communicate with the server, but the server could not find what was requested.

A 404 error is returned by a web server (the machine where a website is hosted) when it cannot find the page you have requested. The most likely cause of this error is a mistyped URL.

404 is not found error. If we typed any sub page link which is not present, it will be redirected to 404 page. We must create such page in our website.

404 is a HTTP status code error "Not Found 404" or "Page Not Found", that indicates server was unable to find the requested address and it is most likely cause of this error is a mistyped URL.
