How the Web works

Viewing a Web page or other resource on the World Wide Web normally begins either by typing the URL of the page into a Web browser, or by following a hypertext link to that page or resource. The first step, behind the scenes, is for the server-name part of the URL to be resolved into an IP address by the global, distributed Internet database known as the Domain name system or DNS. The browser then establishes a TCP connection with the server at that IP address.

Assistive technologies

In addition to dedicated Web content user agents, a wide range of assistive technologies is available to help people with computer accessibility. These technologies can greatly assist access to Web content for people with disabilities. Examples include:

W3C recommendation

The first CSS specification to become an official W3C Recommendation is CSS level 1, published in December 1996.[3] Among its capabilities are support for:

Atom

In reaction to recognized issues with RSS (and because RSS 2.0 is frozen), a third group began a new syndication specification, Atom, in June 2003. Their work was later adopted by the Internet Engineering Task Force (IETF) leading to the publication of a specification (RFC 4287) for the Atom Format in 2005. Work on the Atom Publishing Protocol, a standards-based protocol for posting to publishing tools is ongoing.

The current status of RIA development and adoption

RIAs are still in the early stages of development and user adoption. There are a number of restrictions and requirements that remain:

DOCTYPEs

In order to validate an XHTML document, a Document Type Declaration (or DOCTYPE) may be used. A DOCTYPE declares to the browser which Document Type Definition (DTD) the document conforms to. A Document Type Declaration should be placed before the root element.

Google Mars

Google Mars provides a visible imagery view, like Google Moon, as well as infrared imagery and shaded relief (elevation). Users can toggle between the elevation, visible, and infrared data, in the same manner as switching between map, satellite, and hybrid modes of Google Maps. In collaboration with NASA scientists at Arizona State University, Google has provided the public with data collected from two NASA Mars missions, Mars Global Surveyor and 2001 Mars Odyssey.[19] At present, the Google Earth desktop client cannot access the data, but the feature is in development.

General description

A non-hierarchical keyword categorization system is used on del.icio.us where users can tag each of their bookmarks with a number of freely chosen keywords (cf. folksonomy). A combined view of everyone's bookmarks with a given tag is available; for instance, the URL "http://del.icio.us/tag/wiki" displays all of the most recent links tagged "wiki" (more about navigating tags). Its collective nature makes it possible to view bookmarks added by similar-minded users.

Modules

The primary objective of all RSS modules is to extend the basic XML schema established for more robust syndication of content. This inherently allows for more diverse, yet standardized, transactions without modifying the core RSS specification.

Free implementation

Free (GNU GPL) implementation of social bookmarking tools exists, see Connotea from Nature Journal's Software Group.

Employment

Losing one's employment as a consequence of personal blog commentary about the place of employment has become so commonplace that there is now an informal verb for the event: "dooced". The word dooce originates from the pseudonym of Heather Armstrong, who lost her job after writing satirical accounts of her place of employment on her personal blog. In general, attempts at hiding the blogger's name and/or the place of employment in anonymity have proved ineffective at protecting the blogger.[28] Employees who blog about elements of their place of employment raise the issue of employee branding, since their activities can begin to affect the brand recognition of their employer.

Standards

Many formal standards and other technical specifications define the operation of different aspects of the World Wide Web, the Internet, and computer information exchange. Many of the documents are the work of the World Wide Web Consortium (W3C), headed by Berners-Lee, but some are produced by the Internet Engineering Task Force (IETF) and other organizations.

Tag Clouds in the Media

A website featuring tag clouds and image clouds, chainofthoughts.com was recently highlighted on the BBC website [1] following the Virginia Tech massacre in an article discussing privacy and online mourning. The website featured was used as a place of semi-anonymous mourning, where users could upload images of their school and, using tag clouds, send their condolences.

Multidisciplinary requirements

Web site design crosses multiple disciplines of information systems, information technology and communication design. The website is an information system whose components are sometimes classified as front-end and back-end. The observable content (e.g page layout, user interface, graphics, text, audio) is known as the front-end. The back-end comprises the organization and efficiency of the source code, invisible scripted functions, and the server-side components that process the output from the front-end. Depending on the size of a Web development project, it may be carried out by a multi-skilled individual (sometimes called a web master), or a project manager may oversee collaborative design between group members with specialized skills.
