To create a truly professional and impactful presentation, you can use both traditional programs (for example, Microsoft PowerPoint) and web services. All of them allow you to use images, tables, diagrams, text explanations, etc. in presentations.
There are several programs and services available to help you create effective professional-grade presentations.
Microsoft PowerPoint
The most popular presentation software is Microsoft PowerPoint. The program is part of the Microsoft Office suite. The application has an intuitive interface and many features for creating striking presentations. Each Microsoft PowerPoint presentation consists of multiple slides, which can contain graphs, tables, text, diagrams, and pictures. Users of this application can use various animation effects, transitions between slides, apply musical accompaniment in presentations.
Another plus of Microsoft PowerPoint is that Microsoft has released a free application called Microsoft PowerPoint Viewer that allows you to view presentations on computers that do not have Microsoft PowerPoint installed.
Microsoft PowerPoint is very popular all over the world. The disadvantages of this application include the inability to view the created presentations on operating systems other than Windows (for example, Mac OS).
Google Docs
The Google Docs web service also allows you to create professional-grade presentations. In this case, the user does not have to install additional programs on his computer - all actions to create a presentation are carried out in a browser window. To start creating a presentation, just register on the docs.google.com service and select the "Presentation" item from the "Create" menu. The editor interface used to create presentations on Google Docs is very similar to that of Microsoft PowerPoint. Here, users can also add graphics, tables, web links, and videos to slides.
280 Slides
The 280 Slides web service has functionality similar to Google Docs. It is also a web service, only, unlike Google Docs, it is focused exclusively on creating presentations.
Clients of the service can use videos, pictures, tables, text explanations in their presentations, apply various templates and themes.
Prezi
Prezi is one of the most extraordinary web applications that allows you to create presentations of any complexity. The concept of slides is not used here - all the data in the presentation sits on one giant sheet. To get acquainted with certain data, users move through this sheet using zoom effects (increasing the scale of the presentation).
