Leading networking authority Douglas Comer presents a wide-ranging, self-contained tour of the concepts, principles, and technologies that enable today's Internet to support applications ranging from web browsing to telephony and multimedia. This Fifth Edition has been thoroughly reorganized, revised, and updated: it includes extensive new coverage of topics ranging from wireless protocols to network performance, while reducing or eliminating coverage of older protocols and technologies. Comer begins by illuminating the applications and facilities offered by today's Internet. Next, he systematically introduces the underlying network technologies and protocols that make them possible: low-level data communications; packet switching, LAN, and WAN technologies; and Internet protocols such as TCP, IP, UDP, and IPv6. With these concepts and technologies established, he introduces several of the most important contemporary issues faced by network implementers and managers, including quality of service, Internet telephony, multimedia, network security, and network management. Comer has carefully designed this book to support both top-down and bottom-up teaching approaches. Students need no background in operating systems, and no sophisticated math: Comer relies throughout on figures, drawings, examples, and analogies, "not" mathematical proofs.

     In The Essence of Watercolour Hazel shows how wonderfully versatile and beguiling the medium of watercolour is and how to get the most out of it. Hazel stresses how important it is to understand the characteristics of the medium in order to exploit it to the full.  She encourages the reader to explore the properties of watercolour and to be unafraid of strength of colour and brushstroke.Hazel shows through demonstration and projects that tone is king in watercolour and illustrates how to paint light with the use of shade. Armed with this understanding she demonstrates that watercolour is not such an unforgiving medium after all: accidents and mistakes can be disguised, overridden and corrected.The Essence of Watercolour is a culmination of many years of Hazel's teaching and demonstrating, in which she offers inspirational insights into the secrets of watercolour painting and encourages artists to take their art to the next level.

    It will introduce a new way of looking not only at the treatment of circuits, but also at the treatment of introductory coursework in engineering in general. Using the concept of ''abstraction, '' the book attempts to form a bridge between the world of physics and the world of large computer systems. In particular, it attempts to unify electrical engineering and computer science as the art of creating and exploiting successive abstractions to manage the complexity of building useful electrical systems. Computer systems are simply one type of electrical systems

    It aims to give readers a fundamental overview of the technologies that make up the telecommunications infrastructure.

    The digital transformation demands that we focus our attention on experiences and outcomes. Business leaders and their organizations must shift to keeping promises—no matter how their customers interact with them.But organizations no longer control the conversation. In this era of social and mobile technology, customers, employees, suppliers, and partners are in direct communication with one another. Those personal networks and the brands they’re passionate about influence their decision making and their spending.The workforce has changed too. Employees expect to be able to determine when and how they will work, the technology they’ll use, and the values their company will espouse.Organizations can take part in this conversation only if they recognize how and where it’s happening. Resisting these changes will leave executives, managers, and their companies powerless. Organizations must pivot with and ahead of these social, organizational, and technological shifts or risk being left behind.Technology guru Ray Wang shows how organizations can surf the waves of change—how they can keep their promises. Current trends, when taken seriously, require a new way of thinking about business that includes five key areas:1. Consumerization of technology and the new C-suite2. Data’s influence in driving decisions3. Digital marketing transformation4. The future of work5. Matrix commerceDigital disruption has changed how we do our work. But by mastering these trends you’ll delight your customers with every interaction.

    The authors write: "Oil is the problem. Cars are the solution." We are living in the midst of a Great Awakening in which environmentalists, entrepreneurs, and political leaders are forming new alliances to end our addiction to oil and create new technologies. The days of Big Oil and Big Auto are numbered, according to the authors, who show how we are in the midst of a major transformation from carbon-based energy sources to new fuels and technologies.ZOOM traces the history of the linked industries of oil and automobiles, and how the two have shaped domestic capitalism and the international landscape, creating both progress and peril. They explain how Toyota vanquished American competitors to become the world's largest automobile manufacturer and, more importantly, a leader in hybrid cars using electric power. They take us into the boardrooms of oil executives and show how some are boldly exploring new energy sources while others deny the dangers posed by oil and risk extinction. With wide-ranging analysis and a keen view of the key players in the intersecting worlds of energy and automobiles, authors Iain Carson and Vijay Vaitheeswaran tell the story of what may be the most important challenge facing the industrial world: How to make the transition from the Age of Petroleum to a cleaner and better future.
