web server is a computer that hosts a website on the Internet.

That's the difference between them.

The websites are made from files, medias etc. And all these are stocked on hardware connected to the internet network, accessible by people in the world. This hardwares and the websites contained in it hosted or managed by a computer, a server we call the "webserver".
