Book Synopsis From Mainframes to Smartphones by : Martin Campbell-Kelly

Download or read book From Mainframes to Smartphones written by Martin Campbell-Kelly. This book was released on 2015-06-08. Available in PDF, EPUB and Kindle. Book excerpt: This compact history traces the computer industry from its origins in 1950s mainframes, through the establishment of standards beginning in 1965 and the introduction of personal computing in the 1980s. It concludes with the Internet’s explosive growth since 1995. Across these four periods, Martin Campbell-Kelly and Daniel Garcia-Swartz describe the steady trend toward miniaturization and explain its consequences for the bundles of interacting components that make up a computer system. With miniaturization, the price of computation fell and entry into the industry became less costly. Companies supplying different components learned to cooperate even as they competed with other businesses for market share. Simultaneously with miniaturization—and equally consequential—the core of the computer industry shifted from hardware to software and services. Companies that failed to adapt to this trend were left behind. Governments did not turn a blind eye to the activities of entrepreneurs. The U.S. government was the major customer for computers in the early years. Several European governments subsidized private corporations, and Japan fostered R&D in private firms while protecting its domestic market from foreign competition. From Mainframes to Smartphones is international in scope and broad in its purview of this revolutionary industry.

Book Synopsis System z on the Go: Accessing z/OS from Smartphones by : Alex Louwe Kooijmans

Download or read book System z on the Go: Accessing z/OS from Smartphones written by Alex Louwe Kooijmans. This book was released on 2010-06-10. Available in PDF, EPUB and Kindle. Book excerpt: In this IBM® Redbooks® publication we demonstrate that it is possible to combine the traditional strengths of the mainframe to manage large volumes of data and run business transactions with the Web 2.0 paradigm. We can get simpler interfaces, better integration among different services, lightweight protocols for communication, and much more, together with the availability, security, and reliability of mainframe data. And we will show how mainframe data can be accessed by smartphones such as Android or iPhone. But we can do more to demonstrate how flexible the mainframe platform is. Through the use of pervasive devices it is possible to add new possibilities to mainframe applications, extending System z® capabilities. We can receive notifications in real time, for example, of successful or unsuccessful termination of a TWS job stream, or we can immediately get alerts about abends that occurred in a critical application. This book is another demonstration that the mainframe is alive and kicking and can and should play a key role in modern application architectures.

Book Synopsis A Concise History of Computers, Smartphones and the Internet by : Ernie Dainow

Download or read book A Concise History of Computers, Smartphones and the Internet written by Ernie Dainow. This book was released on 2017-02-01. Available in PDF, EPUB and Kindle. Book excerpt: The very first electronic computers were invented at the end of World War II. They were very large machines that could only be used in special air conditioned rooms. Today, almost everybody carries a computer in their pocket, in their mobile phone. How did all this come about in only 70 years? This book is for people who would like to know the answer to this question. It tells this exciting story, with a lot of pictures. This book is not a complete history, rather it is a concise history that covers the most important people, companies and inventions that led to where we are today. The first chapter covers the evolution of computer hardware - the physical machine. The second chapter focuses on the software - the programs that provide the instructions that tell the hardware what to do. The third chapter covers the most important data networks that were developed so that computers could communicate with each other, ending with the Internet which only became the dominant computer network after 1995. The last chapter on Smartphones traces its history from the discovery of radio waves in the late 19th century to the Apple iPhone. This book does not require a lot of technical knowledge about computers. People who are interested in learning more about how computers actually work can read the companion book “Understanding Computers, Smartphones and the Internet”, by Ernie Dainow.

Book Synopsis IBM by : James W. Cortada

Download or read book IBM written by James W. Cortada. This book was released on 2023-08-01. Available in PDF, EPUB and Kindle. Book excerpt: A history of one of the most influential American companies of the last century. For decades, IBM shaped the way the world did business. IBM products were in every large organization, and IBM corporate culture established a management style that was imitated by companies around the globe. It was “Big Blue, ” an icon. And yet over the years, IBM has gone through both failure and success, surviving flatlining revenue and forced reinvention. The company almost went out of business in the early 1990s, then came back strong with new business strategies and an emphasis on artificial intelligence. In this authoritative, monumental history, James Cortada tells the story of one of the most influential American companies of the last century. Cortada, a historian who worked at IBM for many years, describes IBM's technology breakthroughs, including the development of the punch card (used for automatic tabulation in the 1890 census), the calculation and printing of the first Social Security checks in the 1930s, the introduction of the PC to a mass audience in the 1980s, and the company's shift in focus from hardware to software. He discusses IBM's business culture and its orientation toward employees and customers; its global expansion; regulatory and legal issues, including antitrust litigation; and the track records of its CEOs. The secret to IBM's unequalled longevity in the information technology market, Cortada shows, is its capacity to adapt to changing circumstances and technologies.

Book Synopsis The Routledge Handbook of Waste, Resources and the Circular Economy by : Terry Tudor

Download or read book The Routledge Handbook of Waste, Resources and the Circular Economy written by Terry Tudor. This book was released on 2020-12-27. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook introduces, contextualises, critiques, and discusses a range of perspectives associated with the concept of the circular economy. These perspectives span an array of subjects including economics, environmental policymaking, sociology, environmental science, environmental and industrial engineering, management, international development, and human geography. A fundamental underpinning of the Handbook is that it takes account of a wide range of sectors, as well as geographical perspectives that incorporate both a Global North and Global South world context. This approach is crucial because it is only within such a holistic perspective that the circular economy concept can truly be examined. In addition, these issues are examined both from a theoretical as well as a practical perspective, using real-world case studies for illustration. Given its wide subject, sectoral, and geographical areas of focus, the Handbook should be of value not only for those undertaking research in the field of circular economy, but also stakeholders involved in policymaking, as well as decision-making on the front line.
