Internet hosting service
An Internet hosting service is a service that runs Internet servers, allowing organizations and individuals to serve content to the Internet. There are various levels of service and various kinds of services offered.
A common kind of hosting is web hosting. Most hosting providers offer a combined variety of services. Web hosting services also offer e-mail hosting service, for example. DNS hosting service is usually bundled with domain name registration.
Web hosting technology has been causing some controversy lately as Web.com claims that it holds patent rights to the hosting technology with its 19 patents. Hostopia, a large wholesale host, recently purchased a license to use that technology from web.com for 10% of retail revenues (source). Web.com recently sued Godaddy as well for similar patent infringement (source).
Generic, yet rather powerful, kind of Internet hosting provides a server where the client can run anything he wants (including web servers and other servers) and has an Internet connection with good upstream bandwidth.

- Colocation facilities, which provide just the Internet connection and climate control, but let the client do his own system administration; the most expensive
Limited or application-specific hosting services include:
Internet hosting services include the required Internet connection; they may charge a flat rate per month or charge per bandwidth used — a common payment plan is to charge for the 95th percentile bandwidth.
