These types of associations are fundamental in the functioning of the world Wide Web, since a hyperlink, next to a protocol access to an established data network, allows you to "visit" the different resources available online, either to view or download them to computer.

Every hyperlink has two ends: a source anchor and a destination link. The former are usually highlighted in explorers or internet browsers (in color and underlined, So).

Hyperlink types

There are various types of hyperlink, based on the content or action they perform and their environment:

  • Text hyperlink. Those that start and / or lead to a digital text, or to a specific part of one, such as a chapter or a footnote. This allows the creation of a network of meaning between two or more texts of reading.
