Linking (or hyperlinking) makes objects and documents “connected” to each other. To provide an analogy, consider each slide or presentation to be an individual computer on a network. Individual computers do some awesome work, but the network is much more useful, and increases the worth of each individual computer. In this case, the linking adds the “network” to your PowerPoint files. Linking can happen from one slide to another, or even to another file or a website from within PowerPoint presentations. In each of these linking scenarios, you will find that three factors are always present.
