A public Internet access centre (PIAC) is a site, location, centre of instruction at which Internet access is made available to the public, on a full-time or part-time basis. This may include digital community centres, Internet cafés, libraries, education centres and other similar establishments, whenever they offer Internet access to the general public. All such centres should have at least one public computer for Internet access. It is very useful to classify centres by type, as illustrated by way of example in Figure 1. A further breakdown into private and governmental establishments is also necessary.
