The Web platform is a collection of technologies developed as open standards by the World Wide Web Consortium and other standardization bodies such as the Web Hypertext Application Technology Working Group, the Unicode Consortium, the Internet Engineering Task Force, and Ecma International. It is the umbrella term introduced by the World Wide Web Consortium, and in 2011 it was defined as "a platform for innovation, consolidation and cost efficiencies" by W3C CEO Jeff Jaffe. Being built on The evergreen Web (where rapid, automatic software updates, vendor co-operation, standardization, and competition take place) has allowed for the addition of new capabilities while addressing security and privacy risks. Additionally, developers are enabled to build interoperable content on a cohesive platform. The Web platform includes technologies-computer languages and APIs-that were originally created in relation to the publication of Web pages. WAI-ARIA, ECMAScript, WebGL, Web Storage, Indexed Database API, Web Components, WebAssembly, WebGPU, Web Workers, WebSocket, Geolocation API, Server-Sent Events, DOM Events, Media Fragments, XMLHttpRequest, Cross-Origin Resource Sharing, File API, RDFa, WOFF, HTTP, TLS 1.2, and IRI.
Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser. It defines the content and structure of web content. It is often assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript. Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for its appearance. HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes, and other items. HTML elements are delineated by tags, written using angle brackets. Browsers do not display the HTML tags but use them to interpret the content of the page.
Cascading Style Sheets (CSS) is a simple mechanism for adding style (e.g., fonts, colors, spacing) to Web documents. Scalable Vector Graphics (SVG) is an XML-based vector image format for defining two-dimensional graphics, having support for interactivity and animation. SVG images are defined in a vector graphics format and stored in XML text files. SVG images can thus be scaled in size without loss of quality, and SVG files can be searched, indexed, scripted, and compressed. The XML text files can be created and edited with text editors or vector graphics editors, and are rendered by most web browsers. Early adoption was limited due to lack of support in older versions of Internet Explorer. However, as of 2011, all major desktop browsers began to support SVG. Native browser support offers various advantages, such as not requiring plugins, allowing SVG to be mixed with other content, and improving rendering and scripting reliability. Mobile support for SVG exists in various forms, with different devices and browsers supporting SVG Tiny 1.1 or 1.2. SVG can be produced using vector graphics editors and rendered into raster formats. In web-based applications, Inline SVG allows embedding SVG content within HTML documents. JavaScript is the scripting language of the Web, enabling us to implement all kinds of powerful dynamic features. The usage of JavaScript is not limited to browsers. You can use it in server and console environments with Node. Henry S. Thompson (2011-03-28). "The future of applications: W3C TAG perspectives". W3C. 2013-10-02.

Phone conferencing is key to doing business in a global economy: It brings together associates from around the world for real-time exchanges of important information. In business, information is gold. Without the proper security, disgruntled former employees and savvy hackers can eavesdrop on private phone conferences and sell the privileged information to the highest bidder. A secure phone conferencing setup will have protocols and safeguards in place for controlling access to conference information during and after the call. In this HowStuffWorks article, we'll explain how to set up a secure phone conference that'll keep your business associates informed and corporate thieves at bay. Since phone conferences are "invitation only" events, a certain level of access control is built into the invitation process itself. To invite someone to participate in a phone conference, you need to send him or her a dial-in number and an access code for that individual call.
No one can enter the phone conference without this information. Also, if everyone in the phone conference uses the same access code, then the code tells you nothing about the individual who possesses it. The company CEO has the same access code as a spy from the competition. To tighten access control, it's smart to assign each invitee a PIN (personal identification number) that's tied to their personal information in the phone conferencing system. This way, when the person logs into the phone conference with their PIN, the moderator knows exactly who has joined the call. Most phone-conference systems allow the moderator to do a "roll call" of all the people participating in the phone conference. The moderator can do this either by pressing a special number command on his telephone keypad or through a Web interface. None of the other participants in the phone conference will hear the roll call other than the moderator. Another handy security feature of most phone conferencing services is the ability to lock a conference, blocking any new guests from entering, even if they were invited.
