why do web browsers use so much ram, while the average size of an entire webpage is 2mb?

Question

From what I understand, one could cache 100 web pages (obviously, 2mb is average, but there are much smaller and much larger than that) in about 200mb. 1GB could cache literally 500 web pages.

How come web browsers use so much ram then?

Answer 1

Because the Internet was originally designed as a means of communication. And then it became about selling ads
