What Is a PowerPoint Buffer?
There are a few possible interpretations of "PowerPoint buffer." One is a file that contains malicious code intended to cause a buffer overrun. Another way to think of a buffer for PowerPoint is as a presentation file that sits between two other presentation files.

PowerPoint Vulnerability
-
According to Microsoft, in the Office XP and Office 2003 versions of PowerPoint there is a vulnerability whereby a buffer overrun can be triggered. This code is often found in image files with the .jpg file extension that have been inserted into the buffer PowerPoint. If the PowerPoint file is opened on a computer that has not been updated, the software could crash or malicious code could be executed. Browse to update.microsoft.com to download the updates for your system and prevent buffer PowerPoints from damaging your computer.
Buffer Overflow
-
Software running on a computer is allotted a specific amount of memory with which to work. This memory is known as a buffer, and it holds the data necessary for the program. If the software exceeds the data allotment, that's known as a buffer overflow or buffer overrun. The excess data spills over into unallotted memory, where it can execute arbitrary code not originally intended by the software. This type of security flaw has often been used in malicious software exploits.

Presentation Buffer
-
If you're giving several presentations all together, you might want to include a buffer between different PowerPoint files. One example would be if you and several teammates were all giving presentations together and you wanted have a continuous presentation projected on the screen. You would insert a slide or a few slides that would act as a buffer between the separate presentations and then copy all of the presentations into one, large file. That way the audience will see a seamless presentation and each presenter can have his or her own slides at the ready.
Buffer Slide Design
-
When creating a buffer slide in PowerPoint, you want to include the general elements that are common to all of the separate presentations. If there is one logo for the whole company or one theme for the whole series of presentations, focus on that. You can also include links from the buffer slide to the other presentations so that you can seamlessly navigate through the PowerPoint without having to exit presentations mode. Select an object on the slide and then click "Insert." Click "Hyperlink" and choose "Another Location in this Document." Select the slide that is the beginning of one of the presentation segments and then click "OK." If you repeat this process for all the separate presentations that are grouped into one PowerPoint file you will have a buffer slide that also acts as a navigation slide.
