    A hyperlink, also called just 'a link', is actually a reference in a hypertext document to another document or other resource. It's an intrinsic part of the hypertext transfer protocol (http) for Web, but it's used also in papers, such as.pdf (portable doc file, Adobe Acrobat native format) and in.XML (extended markup language). Hyperlink may be used to get information and save it, see it as a separate document or as an integral part of the research document display.

    The annals of the hyperlink

    The history of the hyperlink started in 1965. Theodore Nelson in 'the Xanadu Project' transposed the idea from fantastic microfilm cross-referencing system in to the computer world. In some articles and books printed from 1964 through 1980 the general concept was changed from linking full microfilm pages to connecting specific lines of computer text. Primary principle was designed to use on single computer machine, however release of DARPA community boosted the theory into making links between files and documents stored on several networked devices. The notion of connecting elements of just one document via hyperlink arose individually, but was quickly combined towards the hyperlink program. Both methods mixed together were fundamental for developing Web.

    So how exactly does an url work?

    An url has two ends, called anchors, and a course. The link starts at the source anchor and details to the destination anchor. While the destination anchor is named the hyperlink target, nevertheless, the name hyperlink is usually used for the resource anchor. Every visitor shows text links significantly subjected (they often draw it with another color). Clicking on the web link displays target file and initiates it.

    Hyperlink - testing the Web

    But hyperlinks aren't just the way we surf the Net. I found out about company website by browsing webpages. Life on the net without search engines is practically impossible to-day, due to amazing quantity of networked information. Many search engines use so-called 'page standing' to calculate which site may possibly contain of use information. This mechanism is mainly centered on hyperlink recognition. Although whole idea of 'page rank' mechanism is more complex, its general strategy is based on a simple rule: the more pages have a hyperlink pointing to the ranked page, the higher rank that page gets. Obviously, each hyperlink has unique value, based on the reputation of the 'resource' site (This means only that when your site can be a target for hyperlink located on the big site like CNet of Microsoft, it has higher page rank when compared to a site with a few hyperlink contacts from individual internet sites). This mechanism is based o-n measuring of hyperlink's quality. Though not perfect, both systems generally is effective enough to determine which internet site has got good content and which has not.
