Stands for "Portable Document Format." PDF is a file format designed to present documents consistently across multiple devices and platforms. It was developed by Adobe 1992 and has since become one of the most widely used formats for saving and exchanging documents.
A PDF file can store a wide variety of data, including formatted text, vector graphics, and raster images. It also contains page layout information, which defines the location of each item on the page, as well as the size and shape of the pages in the document. This information is all saved in a standard format, so the document looks the same, no matter what device or program is used to open it. For example, if you save a PDF on a Mac, it will appear the same way in Windows, Android, and iOS.
The PDF format also supports metadata, such as the document title, author, subject, and keywords. It can store embedded fonts so you do not need to have the appropriate fonts installed to the view the document correctly. PDF documents may also be encrypted so only authorized users can open them.

DOC is a document file format used by Microsoft Word, also used with most word processing software, including OpenOffice. DOC stands for DOCument file. A DOC file can contain formatted text, images, tables, graphs, charts, page formatting, and print settings. With each version of Microsoft Word, the standards for the DOC format change slightly which can cause some compatibility issues.
DOC files are used to save a variety of documents including letters, resumes, essays, and invitations. When you create a document in Word you can choose to save it in the DOC file format. The program then creates a DOC file to store the contents of the document, which can be closed and opened again for further editing. When you are done editing your DOC file you can print it or save it as another file, such as .PDF or .DOT.
