What is the purpose of the 'Slide Master' in PowerPoint?

The purpose of the 'Slide Master' in PowerPoint is to manage overall slide design and layout. This feature allows users to create a consistent look and feel across all slides in a presentation by defining styles for font, colors, backgrounds, headers, footers, and other elements. When changes are made in the Slide Master, they automatically apply to all slides that use that master, ensuring uniformity and saving time when designing presentations.

Using the Slide Master effectively can enhance the professional appearance of a presentation and streamline the design process. It is particularly useful for large presentations where manual adjustments on each slide would be cumbersome. This functionality aids in maintaining a cohesive visual identity and makes it easier to update designs if necessary, as one change can replicate throughout the entire presentation.
