Web

A web, also called a spider's web or cobweb, was a grid-like design created to trap things. Spiders created webs to catch prey, but the term was also applicable in relation to activities and shapes, as well as organizations or subjects that were wide spread.

The Animus was able to generate web and could also create web beings. (TV: The Web Planet, PROSE: Twilight of the Gods) Similarly, the Great Intelligence could create a substance akin to fungus or webbing and sough to envelope the Earth in its great web. (TV: The Web of Fear, HOMEVID: Downtime)

The Internet, although technically different, was also known as the "worldwide web."

The Time Lords ensured the safety of the Web of Time so as to keep the balance of history. (TV: Attack of the Cybermen and others)

Chaotic time loops could have the appearance of a spiral or web. (AUDIO: Spider's Shadow)
