The Individuals’ Level of Computer and Internet Use in Polish Information Society in Comparison to European Average

AbstractNowadays, the devices included in the information and communication technologies, are part of the closest environment. Almost in every house there is a computer and TV, we carry smartphones, pendrives and tablets. Also, we often use cameras, projectors and, more recently, Smartwatches have become increasingly popular. This accumulation of these devices can contribute to increasing our knowledge about the world, or increase the level of some competence. This continuous development and progress in inventing, designing and then creating the above tools, as well as their widespread availability, can be defined as “sustainable information technology”. And this article is an attempt to answer, to which extent information and communication technologies, in particular devices, are used by their users. Are all installed on these devices, programs and applications are regularly used? And as the general application of these technologies affects the knowledge of the equipment and proficiency in their use? Or “sustainable” in the area of information is equal to “sustainable” society
