404 is an HTTP status code. When you visit a web page, your computer is requesting data from a server using Hypertext Transfer Protocol (HTTP).
Before the web page is displayed, your browser sends the web server its HTTP header. The server responds with its HTTP header, which contains the status code.
For a normal web page, the status is 200 (OK). You don't see this because the server just sends you the content of the page.
If you encounter an error, then you see the actual status code, such as 404 Not Found.
The first 4 indicates a client error. The server is saying that you've done something wrong, such as misspell the URL or request a page which is no longer there. (For comparison, a 5xx error indicates a server-side problem, which may be transient; if you try it again, it may work.)
The middle 0 refers to a general syntax error. This could indicate a spelling mistake.
The last 4 just indicates the specific error in the 40x group, which also includes 400: Bad Request, 401: Unauthorized, etc.

Get the 4090 mug.Highway 401-- also known as the MacDonald-Cartier freeway is a stretch of highway in Canada that connects Windsor, Ontario and ends at the Ontario-Quebec border where it becomes Quebec Autoroute 20 before continuing on to Montreal.
The section of highway 401 that passes through Toronto is among the widest and busiest freeways in the world, peaking at 500,000 cars per day (in comparison to Los Angeles' Santa Monica Freeway at 480,000) and expanding to 18 lanes in some sections.
Due to heavy Canada-USA trading, it is also the busiest truck route on the planet.
Highway 401 also crosses the Don River Valley at Hogg's Hollow Bridge, which is the busiest multi-span bridge in North America-surpassing even the Brooklyn Bridge.
