In today’s technology-dependent world, seeking a career in information technology or information systems is both a pragmatic choice and an exciting, forward-thinking option. The demand for people to fill IT and IS positions is high, and the field is constantly evolving, offering plenty of outlets for creative thinkers. This useful guide walks readers through the educational paths that can prepare them most effectively for a job in information technology or information systems. The author weighs the pros and cons of certificate programs, two- and four-year degree programs, online degrees, and graduate degrees. A helpful, highly informative resource.
Now in its third edition, this bestseller offers new data, recommendations, and observations that explore the choices for success available to students in the academic middle.
The approach taken in this book emphasizes the basics of information technology and helps students decide whether to pursue an information technology career. Most students fail to pursue an IT career because of their limited knowledge (sometimes no knowledge) about the area. Similarly, most students pursuing a career in IT do not research the field before their pursuit. This book is purposely designed for students in this category. The book may be offered as a required text for an elective or core course to all bachelor's degree students regardless of specialization. Compared to other textbooks, this text guides students pursuing or wanting to pursue an IT degree/career. Most students often begin their study of IT without knowing the outside and inside of the area. Most of these students can change their minds to pursue a different career path after spending several semesters of studies, a waste of their time. If students are taught from the onset about what an IT career entails and what it takes to become successful, it will significantly help students and not waste their time. This book addresses the issue.
Information, Systems and Information Systems making sense of the field Peter Checkland and Sue Holwell Lancaster University, UK Science-based technology helps to shape our lives, and no technology is more powerful in this respect than that associated with information. But the emerging linked fields of information systems and information technology are still in a very confused state. There is a torrent of technical developments but the concepts which bring structure to the field and make sense of it lag behind. This book seeks to dispel that confusion, and aims to make sense of IS and IT as a whole. Conventional theory bears little relation to the experience most people have with computer-based systems in organizations. Based on real-world experiences in both the private and public sectors, this book from Peter Checkland and Sue Holwell tackles the subject afresh. Information, Systems and Information Systems provides a practice-based approach to the thinking needed to underpin provision of information support in organizations. Starting from fundamentals, the book develops a coherent account of the field. The book is thus a work of conceptual cleansing. It presents a well-argued and tested account of IS and IT which is both holistic and coherent. The sense-making models which emerge can encompass any particular assumptions about the nature of organizational reality and management, whether 'hard' functionalist or 'soft' interpretive ones, though the authors' sympathies are with the latter.
"Ian Fisher has produced a comprehensive and eminently useful volume. Anyone contemplating entering the Information Technology workplace, and even those already there, will benefit from this thoughtfully considered and beautifully organized guidebook . . ."--Dennis Green, Director of Information Technology programs, Columbia University School of Continuing Education.

In today’s fast and competitive world, a program’s performance is just as important to customers as the features it provides. This practical guide teaches developers performance-tuning principles that enable optimization in C++. You’ll learn how to make code that already embodies best practices of C++ design run faster and consume fewer resources on any computer—whether it’s a watch, phone, workstation, supercomputer, or globe-spanning network of servers. Author Kurt Guntheroth provides several running examples that demonstrate how to apply these principles incrementally to improve existing code so it meets customer requirements for responsiveness and throughput. The advice in this book will prove itself the first time you hear a colleague exclaim, “Wow, that was fast. Who fixed something?” Locate performance hot spots using the profiler and software timers Learn to perform repeatable experiments to measure performance of code changes Optimize use of dynamically allocated variables Improve performance of hot loops and functions Speed up string handling functions Recognize efficient algorithms and optimization patterns Learn the strengths—and weaknesses—of C++ container classes View searching and sorting through an optimizer’s eye Make efficient use of C++ streaming I/O functions Use C++ thread-based concurrency features effectively
Presents copy for use as a reference brochure and a 7iveaway sheet to be distributed to guidance counselors to help them direct young people into the growing field of Information Science. Sets forth that Information Science is concerned with the properties, behavior, and flow of information. Describes how it is used, both by individuals and in large systems. Discusses the opportunities in Information Science and outlines three relatively different career areas: (1) Special Librarianship; (2) Licerature Analysis; and (3) Information System Design. Details an educational program appropriate 6or participation in these career areas. Concludes that Information Science is a new but rapidly growing field pushing the frontiers of human knowledge and, thus, 3ontributing to human wellbeing and progress. (Author).

World-renowned economist Klaus Schwab, Founder and Executive Chairman of the World Economic Forum, explains that we have an opportunity to shape the fourth industrial revolu­tion, which will fundamentally alter how we live and work. Schwab argues that this revolution is different in scale, scope and complexity from any that have come before. Characterized by a range of new technologies that are fusing the physical, digital and biological worlds, the developments are affecting all disciplines, economies, industries and governments, and even challenging ideas about what it means to be human. Artificial intelligence is already all around us, from supercomputers, drones and virtual assistants to 3D printing, DNA sequencing, smart thermostats, wear­able sensors and microchips smaller than a grain of sand. But this is just the beginning: nanomaterials 200 times stronger than steel and a million times thinner than a strand of hair and the first transplant of a 3D printed liver are already in development. Imagine “smart factories” in which global systems of manu­facturing are coordinated virtually, or implantable mobile phones made of biosynthetic materials. The fourth industrial revolution, says Schwab, is more significant, and its ramifications more profound, than in any prior period of human history. He outlines the key technologies driving this revolution and discusses the major impacts expected on government, business, civil society and individu­als. Schwab also offers bold ideas on how to harness these changes and shape a better future—one in which technology empowers people rather than replaces them; progress serves society rather than disrupts it; and in which innovators respect moral and ethical boundaries rather than cross them. We all have the opportunity to contribute to developing new frame­works that advance progress.
