The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an HTML or XML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects. DOM methods allow programmatic access to the tree; with them one can change the structure, style or content of a document. Nodes can have event handlers attached to them. Once an event is triggered, the event handlers get executed.
JavaScript, often abbreviated as JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS. As of 2023, 98.7% of websites use JavaScript on the client side for webpage behavior, often incorporating third-party libraries. All major web browsers have a dedicated JavaScript engine to execute the code on users' devices.
Multiple-image Network Graphics (MNG) is a graphics file format, published in 2001, for animated images. Its specification is publicly documented and there are free software reference implementations available.
Netscape Navigator is a discontinued proprietary web browser, and the original browser of the Netscape line, from versions 1 to 4.08, and 9.x. It was the flagship product of the Netscape Communications Corp and was the dominant web browser in terms of usage share in the 1990s, but by around 2003 its user base had all but disappeared. This was partly because the Netscape Corporation did not sustain Netscape Navigator's technical innovation in the late 1990s.
Netscape Communications Corporation was an American independent computer services company with headquarters in Mountain View, California, and then Dulles, Virginia. Its Netscape web browser was once dominant but lost to Internet Explorer and other competitors in the so-called first browser war, with its market share falling from more than 90 percent in the mid-1990s to less than one percent in 2006. An early Netscape employee Brendan Eich created the JavaScript programming language, the most widely used language for client-side scripting of web pages and a founding engineer of Netscape Lou Montulli created HTTP cookies. The company also developed SSL which was used for securing online communications before its successor TLS took over.
ActiveX is a deprecated software framework created by Microsoft that adapts its earlier Component Object Model (COM) and Object Linking and Embedding (OLE) technologies for content downloaded from a network, particularly from the World Wide Web. Microsoft introduced ActiveX in 1996. In principle, ActiveX is not dependent on Microsoft Windows operating systems, but in practice, most ActiveX controls only run on Windows. Most also require the client to be running on an x86-based computer because ActiveX controls contain compiled code.
A browser war is a competition for dominance in the usage share of web browsers. The "first browser war," (1995-2001) pitted Microsoft's Internet Explorer against Netscape's Navigator. Browser wars continued with the decline of Internet Explorer's market share and the popularity of other browsers including Firefox, Google Chrome, Safari, Microsoft Edge and Opera.
This is a comparison of both historical and current web browsers based on developer, engine, platform(s), releases, license, and cost.
IBM WebExplorer was an early web browser designed at IBM facilities in the Research Triangle Park for OS/2.
Netscape Plugin Application Programming Interface (NPAPI) was an application programming interface (API) of the web browsers that allows plugins to be integrated.
Cross-browser compatibility is the ability of a website or web application to function across different browsers and degrade gracefully when browser features are absent or lacking.
In computing, the same-origin policy (SOP) is an important concept in the web application security model. Under the policy, a web browser permits scripts contained in a first web page to access data in a second web page, but only if both web pages have the same origin. An origin is defined as a combination of URI scheme, host name, and port number. This policy prevents a malicious script on one page from obtaining access to sensitive data on another web page through that page's Document Object Model (DOM).
Microsoft Internet Explorer 3 (IE3) is the third, and by now, discontinued, version of the Internet Explorer graphical web browser which was announced in March 1996, and was released on August 13, 1996 by Microsoft for Microsoft Windows and on January 8, 1997 for Apple Mac OS. It began serious competition against Netscape Navigator in the first Browser war. It was Microsoft's first browser release with a major internal development component. It was the first more widely used version of Internet Explorer, although it did not surpass Netscape or become the browser with the most market share. During its tenure, IE market share went from roughly 3–9% in early 1996 to 20–30% by the end of 1997. In September 1997 it was superseded by Microsoft Internet Explorer 4.
The Mozilla Application Suite is a discontinued cross-platform integrated Internet suite. Its development was initiated by Netscape Communications Corporation, before their acquisition by AOL. It was based on the source code of Netscape Communicator. The development was spearheaded by the Mozilla Organization from 1998 to 2003, and by the Mozilla Foundation from 2003 to 2006.
MDL Chime was a free plugin used by web browsers to display the three-dimensional structures of molecules. and was based on the RasMol code.
The World Wide Web is a global information medium which users can access via computers connected to the Internet. The term is often mistakenly used as a synonym for the Internet, but the Web is a service that operates over the Internet, just as email and Usenet do. The history of the Internet and the history of hypertext date back significantly further than that of the World Wide Web.
Comet is a web application model in which a long-held HTTPS request allows a web server to push data to a browser, without the browser explicitly requesting it. Comet is an umbrella term, encompassing multiple techniques for achieving this interaction. All these methods rely on features included by default in browsers, such as JavaScript, rather than on non-default plugins. The Comet approach differs from the original model of the web, in which a browser requests a complete web page at a time.
Google Web Toolkit, or GWT Web Toolkit, is an open-source set of tools that allows web developers to create and maintain JavaScript front-end applications in Java. It is licensed under Apache License 2.0.
The Netscape web browser is the general name for a series of web browsers formerly produced by Netscape Communications Corporation, which eventually became a subsidiary of AOL. The original browser was once the dominant browser in terms of usage share, but as a result of the first browser war, it lost virtually all of its share to Internet Explorer due to Microsoft's anti-competitive bundling of Internet Explorer with Windows.
Netscape Navigator 9 is a discontinued web browser that was produced by the Netscape Communications division of parent AOL, first announced on January 23, 2007. It was the ninth major release of the Netscape line of browsers. After AOL outsourced the development of Netscape Browser 8 to Mercurial Communications in 2004, Netscape Navigator 9 marked the first Netscape browser to be produced in-house since the Netscape 7 suite. It also saw the return of the classic Navigator name, which was previously used during Netscape's heyday between versions 1.0 and 4.08 in the 1990s. Netscape Navigator 9 is based on Mozilla Firefox 2.0.
