Microsoft Office PowerPoint refers to Microsoft's demo software. Users can make presentations on projectors or computers, or they can print them out and make them into films, so they can be used in a wider range of fields.
Microsoft Office PowerPoint can not only create presentations, but also hold face-to-face meetings, conference calls or show presentations to the audience online. What Microsoft Office PowerPoint makes is called a presentation.
Function:
You can add a digital signature to a PowerPoint presentation to help ensure that the content of the distributed presentation will not be changed, or mark the presentation as "final version" to prevent accidental changes. Using content controls, you can create and deploy structured PowerPoint templates to guide users to enter correct information, while helping to protect and retain information that should not be changed in a presentation.
