The test of a nomenclature is, of course, its application to real- life situations. Two simple cases involve home users. If a user accesses the Internet by running a terminal program on their PC and then dials up a public service which provides the Internet applications, then that user has Mediated Internet access. The public service has Client or Full access, but the user does not. On the other hand, users who access via SLIP or PPP are running Internet applications on their own PCs and they have Client Internet access.
Many corporations now have a full-time link to the Internet.
Many corporations today separate their internal internet from the public Internet via a firewall. If a user from the internal internet has a desktop computer and reaches out to the Internet, through the firewall, by running any Internet applications, such as a Web browser, then that user has Client Internet access. Some corporations will not allow this, instead requiring all software which touches the public Internet to be run on specially-administered machines which are part of the corporation's firewall suite of services. Hence, users must make a terminal connection to the special machines, from there running the Internet applications. Such users have Mediated Internet access, the same as home users who dial up a public service.
