Это издание в некотором смысле особенное – прошло ровно 20 лет с момента выхода книги в свет. 20 лет – это немаленький срок, за это время дети наших первых читателей подросли и, возможно, стали интересоваться компьютерными сетями. И, возможно, у них в руках окажется 6-е издание книги «Компьютерные сети. Принципы, технологии, протоколы». Эта книга значительно отличается от той, которую читали их родители. Многое из того, что интересовало читателей конца 90-х годов – например, правило 4-х хабов, согласование сетей IP и IPX или сравнение технологий 100VG-AnyLAN и FDDI, – совсем не упоминается в последних изданиях. За 20 лет немало технологий прошли полный цикл от модного термина и всеобщего признания к практически полному забвению. Каждое новое издание книги в той или иной мере отражало изменения ландшафта сетевых технологий.

Название: Enterprise Cyber Risk Management as a Value Creator: Leverage Cybersecurity for Competitive Advantage

This book will help you learn the importance of organizations treating enterprise cyber risk management (ECRM) as a value creator, a business enabler, and a mechanism to create a competitive advantage. Organizations began to see the real value of information and information technology in the mid-1980s. Forty years later, it’s time to leverage your ECRM program and cybersecurity strategy in the same way. The main topics covered include the case for action with specific coverage on the topic of cybersecurity as a value creator, including how the courts, legislators, and regulators are raising the bar for C-suite executives and board members. The book covers how the board’s three primary responsibilities (talent management, strategy, and risk management) intersect with their ECRM responsibilities. ECRM was once solely focused on managing the downside of risk by defending the organization from adversarial, accidental, structural, and environmental threat sources. Having built the case for action, in the second part, the book details the steps that organizations must take to develop and document their ECRM program and cybersecurity strategy.

Provides a complete and detailed description of the non-terrestrial component in the 5G ecosystem. 5G Non-Terrestrial Networksis the first multi-authored reference dedicated to the integration of non-terrestrial networks (NTN) into the 5G ecosystem. Written by leaders in the development of the 3GPP 5G NTN specification, this authoritative resource addresses all key aspects of non-terrestrial components of 5G systems, including standardization, architecture, protocols, and regulatory considerations. Drawing from their expertise in academic and industrial research and development, the authors introduce fundamental principles of non-terrestrial communications, define the NTN architecture and radio protocol stacks, describe applications to support mobility and radio resource management, and more. The book covers 5G New Radio-based technology for NTN as well as LTE NB-IoT/eMTC, providing a well-rounded understanding of the unique characteristics of 5G-NTN systems. Throughout the text, the authors offer insights on various design approaches, technical choices, and trade-off options. This book aims at providing an overview of this 3GPP-defined “NTN” standard. Aimed at easing the inclusion of NTN elements in the 5G ecosystem, the work was conducted within the 3GPP starting with the identification of the technical challenges and potential solutions to support New Radio (NR) protocols and features over satellite links.

A Breakthrough Introduction to The Next Phase of the Digital Age. In Trivergence, Bob Tapscott, writer, speaker, complex system designer, and former CIO introduces an exciting new concept in explaining how the intersection of Artificial Intelligence (AI), Blockchain, and the Internet of Things (IoT) will transform business and society. He explains the synergies between these technologies and the disruptive potential that they will offer, as well as the challenges and risks to making it happen. He offers an insightful guide through the difficult decisions that businesses and society must make to thrive in a new era where decisions will be difficult, and uncertainties abound. You'll discover how and why AI's power is now exploding, its growth driven by smarter approaches to neural networks trained on a new hardware architecture that can derive its intelligence from ever more massive datasets. AI refers to the simulation of human intelligence in machines, enabling them to perform tasks that had previously required human cognitive functions. From recognizing patterns in vast datasets to making recommendations for decision-making, AI is transforming industries such as healthcare, finance, and manufacturing. AI-powered virtual assistants, self-driving cars, and personalized content recommendations are just a glimpse of its potential. The significance of AI lies in its ability to automate complex tasks, enhance efficiency, and uncover insights hidden within data. Recent advances in Deep Learning have expanded beyond focusing on analyzing complex data sets to make predictions to generate entirely new content in data, text, speech, and image.
