Internet is not an intangible notion. In fact, every Web site, blog forum, document or picture available on the net is stored on a server. In the event, a server fails or is cut down from the network, all the data stored will dispappear from the Internet.

A web host is a service provider which makes its servers available to store data, either for free or not.

For instance, JFG Networks makes its blog software available to create a blog and its servers available to host the blog 24/7.
