Webinar
A webinar is a live, interactive online presentation or seminar broadcast over the internet. Participants join from any location using a web browser or app and can interact with the presenter through chat, polls, or Q&A features. Webinars are widely used for training sessions, product demonstrations, thought leadership events, and virtual conferences. Unlike recorded e-learning, webinars create a sense of real-time connection between presenter and audience.

.pps file extension
A .pps file is a legacy PowerPoint slideshow format that opens directly in presentation mode rather than the editing view. Double-clicking a .pps file launches the slideshow immediately, which made it popular for distributing finished presentations to audiences. The .pps format was later replaced by .ppsx as part of Office 2007's shift to an open XML-based file structure.

Display duration
Display duration in PowerPoint refers to the length of time a slide remains visible before automatically advancing to the next one. Setting a display duration enables auto-play presentations that run without manual input — useful for kiosks, event loops, or self-running demos. Duration settings are configured per slide in the Transitions panel and can be combined with timing controls on individual animations to choreograph a fully automated presentation sequence.

Vocalized pause
A vocalized pause is a filler sound — such as 'um', 'uh', 'er', or 'like' — used involuntarily by speakers when they pause to think or gather their thoughts. While occasional pauses are natural, frequent vocalized pauses can undermine a speaker's credibility, reduce clarity, and make a presentation feel less polished. Reducing vocalized pauses is a common goal in public speaking coaching, and is typically addressed through practice, conscious awareness, and the deliberate use of silent pauses instead.
