What is HTTP 404?
The '''404''' or '''Not Found''' is an [[Hypertext Transfer Protocol|HTTP]] error [[Message (computer science)|message]] meaning the [[server|web server]] could be contacted, but the [[file]] or [[webpage]] trying to be accessed could not be found. It appears when the [[Uniform Resource Locator|URL]] clicked on was moved or renamed, or does not exist (as a result of deletion, for example). [[Category:Internet protocols]]
