A service provider that offers shared hosting or committed hosting of a service or services to customers. Hosting services are most normally used for hosting Web sites but can also be used for hosting files, images,Videos, games and similar content.
In the case of Web site hosting services, there are three main types of hosting offered:
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
