I'm a little stuck... Click here to teach me more about this clue!

'a collection of internet sites?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'global network' is the wordplay.
'global' becomes 'worldwide' (synonyms).
'network' becomes 'web' (synonyms).
'worldwide'+'web'='WORLD WIDE WEB'

'provides' acts as a link.

Can you help me to learn more?

(Other definitions for world wide web that I've seen before include "Surfer's network" , "Tim Berners-Lee's invention" , "www" .)

I've seen this clue in The Irish Times.
