Abstract
National digital culture, computer literacy, information literacy, networks, media, CTBT, data, etc.: names are blurring, intersecting and overlapping to identify new skills, new knowledge that students, doctoral candidates and research teachers would need at a time of digital networks. In this terminological proliferation, ‘digital literacy’ has become the generic term, the hashtag, encompassing all other cultures and practices linked to internet networks. But is a new information medium sufficient to characterise all the realities it affects? Why not talk about “information cultures”, to highlight both the multiplicity of cultures affected by the informational phenomenon and the preeminence of digital information, which can be considered as one of the categories of information?
