What is a provider?

A provider is a company that offers services on the Internet.

While it used to be common for so-called ‘Internet Service Providers’ to offer the full range of possible services (and thus to work only superficially in the individual lines of business), it is now increasingly common for specialized service providers to offer specialized services.

For example, ‘Internet Access Providers’ offer access to the Internet, so-called ‘Webspace Providers’ offer storage space for websites and homepages on the Internet.

Mailix is an e-mail service provider and specializes in providing services related to the transport and management of e-mail messages.
