Description | PDF – is a cross-platform extension necessary for the visualization of printed materials in electronic form. It is developed by Adobe Systems using separate PostScript resources. PDF documents can exist separately from the OS or hardware tools with which they were developed. Files of this format do not have restrictions on the length, several types, and image options, as they allow you to embed various multimedia tools, scan-line, and vector images. They are supported by Adobe Reader and many browsers, providing the plugin is installed. |
Technical details | PDF supports color models CMYK, RGB, shades of gray, and also it has its technical formats for performing the exchange of finished documents. Any file contains a description of a 2D or 3D document with all the necessary components (scan-line, vector graphics, text, and more). The extension does not encode data associated with the software or OS used to develop and view it. |

Description | DOC – is a special extension corresponding to the documents created in the text editor Microsoft World, up to the 2007 version. This format stores information about the formatting of a text document - paragraphs, lists, indents, alignments, and much more. Microsoft Word DOC files can include textual information and numerous images, graphics, scripts, and diagrams. DOC is an extension in the binary file format, which begins with an information block that acts as a key element of the entire collection of data files. Such binary files include a relatively large amount of information about the formatting of a text document. Traditionally, the extension has become widespread for creating text-format documents in a wide range of OS. In this format, files are opened by any, including modern versions of the Word editor or its analogs from free packages like Open Office, Libre Office, or utilities like Corel WordPerfect. |
Technical details | The first versions of the DOC file format prioritized the content of the formatted text. Still, over time, a large number of built-in objects were added to it, among which both diagrams and graphs are found, as well as various media files (sounds, video). Files with the DOC extension can contain data about the merge so that the word processing template can be used together with the table or database. |
