Information and communication technology for development (ICTD) is not new -- numerous important though relatively low-profile projects have been building the foundations of ICTD for many years. What's new are its name and, more important, the increased recognition the field has lately been receiving and its potential for exerting greater influence. In this article the authors explore ICTD and examine the role that computer scientists can play in it. The objective is to convince readers that although achieving all the goals of ICTD will not be easy, even their partial realization could have tremendous impact. Although the challenges are great, ICTD is both intellectually rewarding and very attractive to students at all levels. With several recent reports citing the dwindling numbers of students interested in studying computer science, perhaps ICTD is one answer. It may help motivate a new generation of computer scientists to contribute their knowledge, talents, and energies toward solving some of the world's most pressing problems.

Resumen
After communication, search is the most visible and important aspect of the Internet. The Internet's technical elegance is its anarchy and freedom of information sharing; everyone can add information and express his or her views. Search is also one of the aspects of the Internet that makes it fundamentally different from previous media; interactivity is the other obvious one. There is a plausible argument that search capabilities in the broadest sense have led to increased overall productivity by millions of workers, and thus to recent global economic expansion. In looking at the future of the Internet search, the author focus on four areas that will affect human lives in the coming decades. These are integration of textual search and database technologies; distributed repositories; context; and integration with the physical world. The article concludes that search is the fundamental solution to anarchy and information chaos. In the longer term, the full expression of the power of search depends on the use of context and on exploiting the continuing integration of the Internet into the physical world.
