Hosting (also known as Web site hosting,
Web hosting, and Webhosting) is the
business of housing, serving, and maintaining files such
as images, video or any content accessible via the web
for one or more Web sites. Web hosts are companies that
provide space on a server they own for use by their
clients.
More important than the computer space that is provided for Web site files is the fast connection to the Internet. Most hosting services offer connections on T-carrier system lines. Typically, an individual business hosting its own site would require a similar connection and it would be expensive. Using a hosting service lets many companies share the cost of a fast Internet connection for serving files.
