CoWord
CoWord is a software add-on to Microsoft Word to enable multiple users to edit the same document over the Internet with MS Word. It is a part of the CoOffice suite of collaboration tools for Microsoft Office. CoWord can be considered as a collaborative real-time editor, with the editor being MS Word (which is not distributed with CoWord). To use CoWord, users need to supply their own copies of MS Word. As of August 2010, CoWord has become CodoxWord, released by CodoxWare. Technology One of the main challenges in building collaborative real-time editors is in concurrency control. The concurrency control technology used by CoWord is Operational transformation. Operational transformation (OT) can incorporate concurrent changes made to replicas of the same document. This means systems built with OT allow multiple users to make concurrent changes to the document, and all changes will be incorporated. Other known systems based on Operational transformation are: ACE, Gobby, and Subeth ...

Operational Transformation
Operational transformation (OT) is a technology for supporting a range of collaboration functionalities in advanced collaborative software systems. OT was originally invented for consistency maintenance and concurrency control in collaborative editing of plain text documents. Its capabilities have been extended and its applications expanded to include group undo, locking, conflict resolution, operation notification and compression, group-awareness, HTML/XML and tree-structured document editing, collaborative office productivity tools, application-sharing, and collaborative computer-aided media design tools. In 2009 OT was adopted as a core technique behind the collaboration features in Apache Wave and Google Docs. History Operational Transformation was pioneered by C. Ellis and S. Gibbs in the GROVE (GRoup Outline Viewing Edit) system in 1989. Several years later, some correctness issues were identified and several approaches were independently proposed to solve these issues, w ...

Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Word Processor
A word processor (WP) is a device or computer program that provides for input, editing, formatting, and output of text, often with some additional features. Word processor (electronic device), Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers. The functions of a word processor program fall somewhere between those of a simple text editor and a fully functioned desktop publishing program. However, the distinctions between these three have changed over time and were unclear after 2010. Background Word processors did not develop ''out'' of computer technology. Rather, they evolved from mechanical machines and only later did they merge with the computer field. The history of word processing is the story of the gradual automation of the physical aspects of writing and editing, and then to the refinement of the technology to make it available to corporations and Indi ...

Freeware
Freeware is software, most often proprietary, that is distributed at no monetary cost to the end user. There is no agreed-upon set of rights, license, or EULA that defines ''freeware'' unambiguously; every publisher defines its own rules for the freeware it offers. For instance, modification, redistribution by third parties, and reverse engineering are permitted by some publishers but prohibited by others. Unlike with free and open-source software, which are also often distributed free of charge, the source code for freeware is typically not made available. Freeware may be intended to benefit its producer by, for example, encouraging sales of a more capable version, as in the freemium and shareware business models. History The term ''freeware'' was coined in 1982 by Andrew Fluegelman, who wanted to sell PC-Talk, the communications application he had created, outside of commercial distribution channels. Fluegelman distributed the program via a process now termed '' shareware''. ...

Microsoft Office
Microsoft Office, or simply Office, is the former name of a family of client software, server software, and services developed by Microsoft. It was first announced by Bill Gates on August 1, 1988, at COMDEX in Las Vegas. Initially a marketing term for an office suite (bundled set of productivity applications), the first version of Office contained Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. Over the years, Office applications have grown substantially closer with shared features such as a common spell checker, Object Linking and Embedding data integration and Visual Basic for Applications scripting language. Microsoft also positions Office as a development platform for line-of-business software under the Office Business Applications brand. It contains a word processor (Word), a spreadsheet program (Excel) and a presentation program (PowerPoint), an email client (Outlook), a database management system (Access), and a desktop publishing app (Publisher).

Collaborative Real-time Editor
A collaborative real-time editor is a type of collaborative software or web application which enables real-time collaborative editing, simultaneous editing, or live editing of the same digital document, computer file or cloud-stored data – such as an online spreadsheet, word processing document, database or presentation – at the same time by different users on different computers or Mobile devices in healthcare, mobile devices, with automatic and nearly instantaneous merging of their edits. Real-time editing performs automatic, periodic, often nearly instantaneous synchronization of edits of all online users as they edit the document on their own device. This is designed to avoid or minimize edit conflicts. With asynchronous collaborative editing (i.e non-real-time, delayed or offline), each user must typically manually submit (publish, push or commit), update (refresh, pull, download or sync) and (if any edit conflicts occur) merge their edits. Due to the delayed nature o ...

Concurrency Control
In information technology and computer science, especially in the fields of computer programming, operating systems, multiprocessors, and databases, concurrency control ensures that correct results for Concurrent computing, concurrent operations are generated, while getting those results as quickly as possible. Computer systems, both software and computer hardware, hardware, consist of modules, or components. Each component is designed to operate correctly, i.e., to obey or to meet certain consistency rules. When components that operate concurrently interact by messaging or by sharing accessed data (in Computer memory, memory or Computer data storage, storage), a certain component's consistency may be violated by another component. The general area of concurrency control provides rules, methods, design methodologies, and Scientific theory, theories to maintain the consistency of components operating concurrently while interacting, and thus the consistency and correctness of the who ...

ACE (editor)
Ace (from Ajax.org Cloud9 Editor) is a standalone code editor written in JavaScript. The goal is to create a web-based code editor that matches and extends the features, usability, and performance of existing native editors such as TextMate, Vim, or Eclipse. It can be easily embedded in any web page and JavaScript application. Ace is developed as the primary editor for Cloud9 IDE and as the successor of the Mozilla Skywriter project. History Previously known as Bespin or lately Skywriter, it is now known as Ace (Ajax.org Cloud9 Editor). Bespin and Ace started as two independent projects both aiming to build a no-compromise code editor component for the web. Bespin started as part of Mozilla Labs and was based on the tag, while Ace is the Editor component of the Cloud9 IDE and is using the DOM for rendering. After the release of Ace at JSConf.eu 2010, in Berlin, the Skywriter team decided to merge Ace with a simplified version of Skywriter's plugin system and some of Skywrite ...

Subethaedit
SubEthaEdit is a collaborative real-time editor designed for Mac OS X. The name comes from the Sub-Etha communication network in ''The Hitchhiker's Guide to the Galaxy'' series. History SubEthaEdit was first released under the name Hydra in early 2003 but, for legal reasons, the name was changed to SubEthaEdit in late 2004. The first version of Hydra was built in just a few months with the intent of winning an Apple Design Award, which it did at Apple's Worldwide Developers Conference 2003. In 2007, TheCodingMonkeys licensed the "Subetha Engine" to Panic for use in Coda. In June 2014, SubEthaEdit 4 was released, distributed exclusively in the Mac App Store. With version 5 released in 2019, the application became free and open source, under the MIT license. Features Apart from the usual text-editing capabilities, collaborative editing is one of SubEthaEdit's key features. The collaboration is document-based, non-locking, and non-blocking. Anyone participating in the collabor ...
