... is the body of methods and tools by which communications and computing technologies are applied to acquire and transform data, and to present and disseminate information to increase the effectiveness of the modern enterprise.Computational Science --- which operates in the intersection of mathematics, statistics, computer science and the applications areas --- provides scientific underpinnings for IT. In particular,
Computational Science is that part of Information Technology specifically devoted to developing mathematical, statistical, and computational methods and tools for extracting information from industry, science, engineering, and management data.The two divisions within ITL chartered to provide leadership in computational science --- the Mathematical and Computational Sciences Division and the Statistical Engineering Division --- have responsibility to support IT research specific to the ITL, and also to collaborate with NIST scientists and engineers on the development and application of mathematical, statistical, and computational methods for problems of interest to NIST, with the overall goal of enhancing the competitiveness of US industry.
