| Sự miêu tả | iWork is an office suite of applications created by Apple Inc. for its macOS and iOS operating systems, and also available cross-platform through the iCloud website. Numbers is a part of the iWork productivity suite alongside Keynote and Pages. Numbers is available for iOS, and Mac OS X v10.12 or newer. | The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. |
| Chi tiết kỹ thuật | Numbers uses a free-form "canvas" approach that demotes tables to one of many different media types placed on a page. Other media, like charts, graphics and text, are treated as peers. In comparison, traditional spreadsheets like Microsoft Excel use the table as the primary container, with other media placed within the table. | The PDF combines three technologies: A subset of the PostScript page description programming language, for generating the layout and graphics. A font-embedding/replacement system to allow fonts to travel with the documents. A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate. |
