Designed for every businessperson who wants to understand how information technology is used in business today. Not an exhaustive or comprehensive list, but a selective guide to 150 key terms and concepts. Provides a vocabulary of core IT terms, and explains their relevance to managers in easily understood language. Also puts these terms into context: instead of elaborating on how bugs and viruses work, cites famous examples of disastrous bugs and explains why they are an unavoidable part of the new technology. Instead of explaining the technical differences in operating systems like the OS/2 or UNIX, describes the key features and advantages of each. Includes an introductory essay that gives an excellent overview of information technology in the organization. Keen shows that just as managers must be familiar with basic accounting techniques or basic marketing principles, so too must they understand the basics of IT. They can no longer afford to simply delegate critical IT strategic decisions to technical professionals.
