Hosting (also known as Web site hosting, Web hosting, and Webhosting) is the business of housing, serving, and maintaining files for one or more Web sites. 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.
In the case of Web site hosting services, there are three main types of hosting available: 1) Shared Web hosting, where a large number of Web sites are typically housed on the same server; 2) Dedicated Web hosting, where an entire server is leased and reserved for a single Web site; and 3) Virtual Private Server hosting, a hybrid of the first two options in which a Web site is hosted on its own virtual server so that it won’t be affected by the Web sites of other customers.
