This is called a semantic network. Thus the more links that can be formed between existing knowledge and new knowledge, goes the theory, the better the information will be comprehended and the easier learning will be. B. Think of it as a database modelled after a node linked network. That is, information units are similar to nodes which are connected by links. Each node, when displayed, corresponds to a separate window on the monitor screen.
Links are usually appear represented as icons in the window.
Thus when a user activates a link by a device such as a mouse, a node, or window, explodes or appears onto the screen with the information. Hypertext nodes - unlike a conventional paragraph, a node may have more than two neighbours. These neighbours are other nodes which are connected to it by links. Each node is a single contained unit, or idea and the user may choose to follow any links to any number of nodes and from the new node to any number of any other nodes. Nodes may also have subordinate or superordinate relationships which allow for a complete structuring of hierarchical relationships.
