Slide transition and custom slide show explain?

Answer 1

A slide transition is the process of changing from one slide to another in a presentation. At its simplest, one slide can disappear and the next one immediately appear. You can do many kinds of transitions, like a slide moving in from one side and pushing the other slide out. You can also set the amount of time a transition takes.

A custom show is a slide show that you can make from your full set of slides by picking some and displaying them. They can even be picked in a different order. Sometimes you might have variations of a slide show for different audiences. There might be some slides that you show to some that you would not show to others. Instead of creating several individual slide shows as separate files, you can create one slide show and create a few custom shows from the set of slides you have, without creating a new file.
