Prerequisites and factors of the information and computer sciences convergence

Analytical review is devoted to a problem of convergence of information and computer sciences, and also to interrelations of these sciences with information and communication technologies (ICT). Interest in the convergence problem arouse more than forty years ago. One of its formulations — computer and information sciences: a new basic discipline-became the title of the work by S. Gorn published in 1963. At present, the urgency of a convergence problem has essentially increased. Considered in the review priority guidelines of research and development on ICT within 7th Frame Program of the European Union accepted for the period of 2007–2013 are the evidence of it. In the review, priority ICT guidelines are positioned as external factors of convergence. Except for external factors, historical preconditions of convergence of information and computer sciences are viewed. Factors and preconditions of convergence are considered in a context of development of scientific basis of new ICT generations' creation.
