ABSTRACT
Computers and the Internet have opened a world of shared data. In school or in a business, you can collaborate with a group to write a paper or a lab report. In some cases, one group member might write the entire document, or you might sit together in a public computer cluster and write the paper together. Alternatively, members of the group might take turns working on the same –le by sharing it electronically. Sharing –les via a network can take group projects to an entirely new level of eÐciency. No longer do you need to run out in the rain, disk in hand, to a friend’s dorm so that she can edit your dra¤ of your group paper. Instead, you and she can separately log on to a computer network, you can exchange –les, and you are one step closer to a –nished paper or report. But how do Web services and computer networks make all of this sharing possible?
