IBM's vision of the future of computing and how its evolving technologies, product lines, and services fit into that future are the subject of this broad overview of the world’s largest computer company. It provides full coverage of IBM's e-business strategy to leverage Internet technology and of its new emphasis on IBM Global Services, its fast-growing consulting business. Profiles of IBM's personal computer, RS/6000, NUMA-Q, AS/400, and S/390 families, developed through brief case studies, show how each fits in a contemporary business context. New terms are defined as they are introduced, and a companion Web site accessible only to buyers of this book provides the latest news and additional resources related to IBM technology and product lines.
