This article deals with the integration of information technology tools and services into the economies of European countries and compares the degrees to which ICT has penetrated into their economies and societies. Our evaluation of the penetration of ICT into economies within this article works primarily from the standpoint of infrastructure-services penetration. These services are today typically expressed through computer-network connection speeds. For our comparison of the nations of Europe, and of the V4 nations, we utilized public, open data for 2010–2014 provided by various institutions. These include primarily Eurostat, the Office of the European Union, the World Bank, and the Czech Statistical Office. In terms of methodology, the multi-criteria TOPSIS analysis method is used for comparison. A comparison of the penetration of technological infrastructure into the V4 countries between 2010 and 2014 and a comparison of them with the EU average is provided at the end of the article.
