A hyperlink is the connection between two hypertext nodes. In simple terms, it is a backlink between two documents on the World Wide Web.
When Tim Berners-Lee published his proposal “Information Management: A Proposal” at CERN in 1990, his aim was to find a solution to an internal problem at the institute using a decentralised hypertext system.
In his conclusion, he seeks to create linked (hypertext) information systems, in which the general availability and platform independence of information are the most important assets.
In order to link these systems and documents without restricting them, he proposes the use of links between these nodes.
This system proposed by Berners-Lee has evolved over the years into the World Wide Web, and the hyperlink is thus the fancy name of the backlink we are all familiar with.
