Powerpoint

Hi Edward, thanks for the query. The slide master is used to house any repeating elements such as background images, logos, or bullet levels and structure that crop up in a presentation. Essentiallly, if you have a 400 slide presentation you put the company logo on the slide master instead of inserting it manually on each slide. Therefore, if the logo or any other repeating element changes, you can replace it just on the slide master and the entire presentation will be updated.

Hope this helps,

Anthony
