Description: PPT is a file format used for creating presentations on Microsoft Windows computers. It was first introduced in 1987 together with the release of PowerPoint. PPT is a binary file format. Starting from PowerPoint 2007, it was replaced by the PPTX format which uses OpenXML. However, PPT files are still supported by later versions of PowerPoint.
Technical Details: A PPT file is an editable slideshow created by PowerPoint. It is also possible to use another presentation program, such as Apple Keynote, OpenOffice Impress, or make a presentation out of a PDF file. Formatted text, lists, images, video clips, sound effects, music—all these elements can be included in the PPT file. Creating a PPT slideshow commonly starts from choosing and completing a software's built-in template.

Description: Portable Document Format (PDF) was invented in the 1990s. In 1991, Adobe cofounder Dr. John Warnock came up with the idea called "The Camelot Project". This project launched the paper-to-digital revolution. The goal was to allow anyone to use documents from any app, share them electronically anytime and anywhere and view and print them on any machine. The idea was completely implemented by 1992. The main benefit of using PDF is that the file looks the same way as the original document, i.e. PDFs preserve the original view of the data you include in the file. Data in the original file, including text, graphics, spreadsheets, and more are able to be combined in a single file.
Technical Details: A PDF is a 7-bit ASCII file. Some elements may contain binary content. A PDF file has a header with the number and the version of the format that is a subset of a "Carousel" Object Structure format. A COS tree file includes the following types of objects: boolean values, numbers, strings, names, arrays, dictionaries, streams, and the null object.
