Описание: Information systems are critical to the health, economy, and security of the nation. To support these systems, the federal government invested over $90 billion in information technology (IT) in fiscal year 2016. However, prior IT expenditures have too often produced failed projects. The objective of Chapter 1 is to determine the extent to which federal agencies identify IT contracts and how much is invested in them, and federal agency CIOs are reviewing and approving IT acquisitions. The federal government spends tens of billions of dollars each year on IT products and services. Competition is a key component to achieving the best return on investment for taxpayers. Chapter 2 examines the extent that agencies used non-competitive contracts for IT, the reasons for using non-competitive contracts for selected IT procurements, the extent to which IT procurements at selected agencies were bridge contracts, and the extent to which IT procurements were in support of legacy systems. The federal government plans to spend over $90 billion in fiscal year 2019 on IT. About 80 percent of this amount is used to operate and maintain existing IT investments, including aging (also called legacy) systems. As they age, legacy systems can be more costly to maintain, more exposed to cybersecurity risks, and less effective in meeting their intended purpose. Chapter 3 reviews federal agencies legacy systems. This chapter identifies the most critical federal legacy systems in need of modernisation and evaluates agency plans for modernising them, and identifies examples of legacy system modernisation initiatives that agencies considered successful.

Описание: The main emphasis of this work is the mathematical theory of quantum channels and their entropic and information characteristics. Quantum information theory is one of the key research areas, since it leads the way to vastly increased computing speeds by using quantum systems to store and process information. Quantum cryptography allows for secure communication of classified information. Research in the field of quantum informatics, including quantum information theory, is in progress in leading scientific centers throughout the world.The past years were marked with impressive progress made by several researchers in solution of some difficult problems, in particular, the additivity of the entropy characteristics of quantum channels. This suggests a need for a book that not only introduces the basic concepts of quantum information theory, but also presents in detail some of the latest achievements.

Описание: The book is addressed to young people interested in computer technologies and computer science. The objective of this book is to provide the reader with all the necessary elements to get him or her started in the modern field of informatics and to allow him or her to become aware of the relationship between key areas of computer science. The book is addressed not only to future software developers, but also to all who are interested in computing in a widely understood sense. The authors also expect that some computer professionals will want to review this book to lift themselves above the daily grind and to embrace the excellence of the whole field of computer science. Unlike existing books, this one bypasses issues concerning the construction of computers and focuses only on information processing. Recognizing the importance of the human factor in information processing, the authors intend to present the theoretical foundations of computer science, software development rules, and some business aspects of informatics in non-technocratic, humanistic terms.
