Computers, communications, digital information, softwareâ€"the constituents of the information ageâ€"are everywhere. Being computer literate, that is technically competent in two or three of today's software applications, is not enough anymore. Individuals who want to realize the potential value of information technology (IT) in their everyday lives need to be computer fluentâ€"able to use IT effectively today and to adapt to changes tomorrow. Being Fluent with Information Technology sets the standard for what everyone should know about IT in order to use it effectively now and in the future. It explores three kinds of knowledgeâ€"intellectual capabilities, foundational concepts, and skillsâ€"that are essential for fluency with IT. The book presents detailed descriptions and examples of current skills and timeless concepts and capabilities, which will be useful to individuals who use IT and to the instructors who teach them.

There are two different, interdependent components of IT that are important to a CIO: strategy, which is long-term; and tactical and operational concerns, which are short-term. Based on this distinction and its repercussions, this book clearly separates strategy from day-to-day operations and projects from operations – the two most important functions of a CIO. It starts by discussing the ideal organization of an IT department and the rationale behind it, and then goes on to debate the most pressing need – managing operations. It also explains some best industry standards and their practical implementation, and discusses project management, again highlighting the differences between the methodologies used in projects and those used in operations. A special chapter is devoted to the cutover of projects into operations, a critical aspect seldom discussed in detail. Other chapters touch on the management of IT portfolios, project governance, as well as agile project methodology, how it differs from the waterfall methodology, and when it is convenient to apply each. Taking the fundamental principles of IT service management and best practices in project management, the book offers a single, seamless reference for IT managers and professionals. It is highly practical, explaining how to apply these principles based on the author’s extensive experience in industry.

Information Technology for Small Business: Managing the Digital Enterprise provides an overview of how small and medium business enterprises (SMEs) can use flexibility, agility, and anticipation strategies to better utilize information technology and knowledge management. Because small and medium businesses tend to be late technology adopters, they could miss versatile and strategic workforce advantages that enable them to achieve higher efficiency and effectiveness through technology. This book shows these SMEs new technology trends that can transform the nature of their operations both in an evolutionary business path and through revolutionary opportunities. Information Technology for Small Business: Managing the Digital Enterprise applied correctly to small and medium business can be used as a strategic tool to reach growth and profit goals for the SMEs competing in a very dynamic and global marketplace. Examples include: identifying ways that IT can be used to develop strong relationships with customers and suppliers, and how to select the best technologies for business needs. Information Technology for Small Business: Managing the Digital Enterprise targets SME owners, educators, and practitioners working in the related fields of management, IT, IS, and CS-related disciplines. Advanced-level students and policy makers focusing on SMEs will also find this book valuable in terms of main concepts for discussion.

his textbook is designed to teach a first course in Information Technology (IT) to all undergraduate students. In view of the all-pervasive nature of IT in today’s world a decision has been taken by many universities to introduce IT as a compulsory core course to all Bachelor’s degree students regardless of their specialisation. This book is intended for such a course. The approach taken in this book is to emphasize the fundamental “Science” of Information Technology rather than a cook book of skills. Skills can be learnt easily by practice with a computer and by using instructions given in simple web lessons that have been cited in the References. The book defines Information Technology as the technology that is used to acquire, store, organize, process and disseminate processed data, namely, information. The unique aspect of the book is to examine processing all types of data: numbers, text, images, audio and video data. As IT is a rapidly changing field, we have taken the approach to emphasize reasonably stable, fundamental concepts on which the technology is built. A unique feature of the book is the discussion of topics such as image, audio and video compression technologies from first principles. We have also described the latest technologies such as ‘e-wallets’ and ‘cloud computing’. The book is suitable for all Bachelor’s degree students in Science, Arts, Computer Applications, and Commerce. It is also useful for general reading to learn about IT and its latest trends. Those who are curious to know, the principles used to design jpg, mp3 and mpeg4 compression, the image formats—bmp, tiff, gif, png, and jpg, search engines, payment systems such as BHIM and Paytm, and cloud computing, to mention a few of the technologies discussed, will find this book useful. KEY FEATURES • Provides comprehensive coverage of all basic concepts of IT from first principles • Explains acquisition, compression, storage, organization, processing and dis-semination of multimedia data • Simple explanation of mp3, jpg, and mpeg4 compression • Explains how computer networks and the Internet work and their applications • Covers business data processing, World Wide Web, e-commerce, and IT laws • Discusses social impacts of IT and career opportunities in IT and IT enabled services • Designed for self-study with every chapter starting with learning objectives and concluding with a comprehensive summary and a large number of exercises.

Information Technology (IT) is conquering the world. It affects our jobs, our lives as private citizens, and society. Its impact is greater than other technologies, such as railways, personal cars, and the telephone. However, while most can understand the potential and constraints of these technologies, IT is often experienced as a “black box,” producing its effects without giving a clue as to how they are achieved. The aim of How Information Technology Is Conquering the World is to open this box and to offer a basic knowledge of the technology and how it works. We will then understand why IT can put toll both operators, metro train engineers, and stockbrokers out of a job, but at the same time have limited impact on bus drivers, nurses, and teachers. How Information Technology Is Conquering the World focuses on the interface between the technologies and the real world in order to explore not only where these technologies have their advantages but also where their limitations become apparent. The difficulty of introducing a new technology is emphasized with the practical goal of enabling readers to use technology to full advantage. This book is useful for those involved in, affected by, or interested in the technology; for students taking an introductory course in computing; and for managers and others who are interested in seeing how this rapidly evolving technology will affect their lives, jobs, and businesses now and in the future.
