ver, just like people do. But Valerie can't do everything a person can do. She can't eat or drink, breathe, perform other bodily functions, hurt people, have sex, put her head under water, or take any water or other liquids into her head or mouth. She can't drive a car or run a lawn mower because she's not allowed to go outside. She can't do physical actions that people can't do, and she doesn't sleep. ICT Trends Driving the Broadband Evolution Grid Computing Grid computing is the key to the future of e-business, and it represents the next step in the development of the Internet as a real-time computing platform. Today, some 80% to 90% of processing capacity-whether PC workstation or main- frame-is unused. Grid computing aims to remedy this situation. The vision of grid computing is to bundle computing resources into a network and, similarly to electricity, allow processing power to flow from the socket wher- ever and whenever it is needed. Grid computing is emerging as the next-generation concept of the World Wide Web, something that's being called the World Wide Grid. Rather than simply engaging in information interchange, the future Internet will enable access to high-performance computers anytime and everywhere in the world. Grid-computing technology will be of particular use in performing resource- intensive tasks and solving complex calculations. As you can well imagine, security will be a critical issue with grid computing. Grid computing has three main applications areas: On-demand computing grids-On-demand computing grids connect the computing resources owned by different groups and execute processing- intensive applications much faster. A growing range of industries require the intensive processing power of grid computing, including the research and scientific communities, automobile manufacturing, electronic design companies, life sciences, energy, and financial services. Data storage grids-For commercial and industrial use, computers must be able to automatically and transparently locate computers wit
