Microsoft Word is a word processor developed by Microsoft. It was first released on October 25, 1983, under the name Multi-Tool Word for Xenix systems. Subsequent versions were later written for several other platforms including: IBM PCs running DOS (1983), Apple Macintosh running the Classic Mac OS (1985), AT&T UNIX PC (1985), Atari ST (1988), OS/2 (1989), Microsoft Windows (1989), SCO Unix (1990), macOS (2001), Web browsers (2010), iOS (2014) and Android (2015). Using Wine, versions of Microsoft Word before 2013 can be run on Linux.
Portable Document Format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it. PDF has its roots in "The Camelot Project" initiated by Adobe co-founder John Warnock in 1991. PDF was standardized as ISO 32000 in 2008. The last edition as ISO 32000-2:2020 was published in December 2020.
PostScript is a page description language and dynamically typed, stack-based programming language. It is most commonly used in the electronic publishing and desktop publishing realm, but as a Turing complete programming language, it can be used for many other purposes as well. PostScript was created at Adobe Systems by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton from 1982 to 1984. The most recent version, PostScript 3, was released in 1997.
In digital printing, a page description language (PDL) is a computer language that describes the appearance of a printed page in a higher level than an actual output bitmap. An overlapping term is printer control language, which includes Hewlett-Packard's Printer Command Language (PCL). PostScript is one of the most noted page description languages. The markup language adaptation of the PDL is the page description markup language.
A word processor is an electronic device for text, composing, editing, formatting, and printing.
In computing, WYSIWYG, an acronym for What You See Is What You Get, refers to software which allows content to be edited in a form that resembles its appearance when printed or displayed as a finished product, such as a printed document, web page, or slide presentation. WYSIWYG implies a user interface that allows the user to view something very similar to the result while the document is being created. In general, WYSIWYG implies the ability to directly manipulate the layout of a document without having to type or remember names of layout commands.
Xerox Holdings Corporation is an American corporation that sells print and digital document products and services in more than 160 countries. Xerox is headquartered in Norwalk, Connecticut, though it is incorporated in New York with its largest population of employees based around Rochester, New York, the area in which the company was founded. The company purchased Affiliated Computer Services for $6.4 billion in early 2010. As a large developed company, it is consistently placed in the list of Fortune 500 companies.
Ventura Publisher was the first popular desktop publishing package for IBM PC compatible computers running the GEM extension to the DOS operating system. The software was originally developed by Ventura Software, a small software company founded by John Meyer, Don Heiskell, and Lee Jay Lorenzen, all of whom met while working at Digital Research. It ran under an included run-time copy of Digital Research's GEM.
John Edward Warnock was an American computer scientist, inventor, technology businessman, and philanthropist best known for co-founding Adobe Systems Inc., the graphics and publishing software company, with Charles Geschke in 1982. Warnock was President of Adobe for his first two years and chairman and CEO for his remaining sixteen years at the company. Although he retired as CEO in 2001, he continued to co-chair the Adobe Board of Directors with Geschke until 2017. Warnock pioneered the development of graphics, publishing, web and electronic document technologies that have revolutionized the field of publishing and visual communications.
In computing, a compound document is a document that “combines multiple document formats, either by reference, by inclusion, or both.” Compound documents are often produced using word processing software, and may include text and non-text elements such as barcodes, spreadsheets, pictures, digital videos, digital audio, and other multimedia features.
DjVu is a computer file format designed primarily to store scanned documents, especially those containing a combination of text, line drawings, indexed color images, and photographs. It uses technologies such as image layer separation of text and background/images, progressive loading, arithmetic coding, and lossy compression for bitonal (monochrome) images. This allows high-quality, readable images to be stored in a minimum of space, so that they can be made available on the web.
Bravo was the first WYSIWYG document preparation program. It provided multi-font capability using the bitmap displays on the Xerox Alto personal computer. It was produced at Xerox PARC by Butler Lampson, Charles Simonyi and colleagues in 1974.
Mixed raster content (MRC) is a method for compressing images that contain both binary-compressible text and continuous-tone components, using image segmentation methods to improve the level of compression and the quality of the rendered image. By separating the image into components with different compressibility characteristics, the most efficient and accurate compression algorithm for each component can be applied.
Open XML Paper Specification is an open specification for a page description language and a fixed-document format. Microsoft developed it as the XML Paper Specification (XPS). In June 2009, Ecma International adopted it as international standard ECMA-388.
JBIG2 is an image compression standard for bi-level images, developed by the Joint Bi-level Image Experts Group. It is suitable for both lossless and lossy compression. According to a press release from the Group, in its lossless mode JBIG2 typically generates files 3–5 times smaller than Fax Group 4 and 2–4 times smaller than JBIG, the previous bi-level compression standard released by the Group. JBIG2 was published in 2000 as the international standard ITU T.88, and in 2001 as ISO/IEC 14492.
ABBYY FineReader PDF is an optical character recognition (OCR) application developed by ABBYY, with support for PDF file editing since v15. The program runs under Microsoft Windows 7 or later, and Apple macOS 10.12 Sierra or later. The first version was released in 1993.
A photocopier is a machine that makes copies of documents and other visual images onto paper or plastic film quickly and cheaply. Most modern photocopiers use a technology called xerography, a dry process that uses electrostatic charges on a light-sensitive photoreceptor to first attract and then transfer toner particles onto paper in the form of an image. The toner is then fused onto the paper using heat, pressure, or a combination of both. Copiers can also use other technologies, such as inkjet, but xerography is standard for office copying.
A reflowable document is a type of electronic document that can adapt its presentation to the output device. Typical prepress or fixed page size output formats like PostScript or PDF are not reflowable during the actual printing process because the page is not resized. For end users, the World Wide Web standard, HTML is a reflowable format as is the case with any resizable electronic page format.
The Xerox Character Code Standard (XCCS) is a historical 16-bit character encoding that was created by Xerox in 1980 for the exchange of information between elements of the Xerox Network Systems Architecture. It encodes the characters required for languages using the Latin, Arabic, Hebrew, Greek and Cyrillic scripts, the Chinese, Japanese and Korean writing systems, and technical symbols.
Larry Melvin Masinter is an early internet pioneer and ACM Fellow. After attending Stanford University, he became a Principal Scientist of Xerox Artificial Intelligence Systems and author or coauthor of 26 of the Internet Engineering Task Force's Requests for Comments.
