A Brief Look Back at the History of the Internet
g g g g g g g g g



It is hard to explain to someone born after the turn of the century how people
g g g g g g g g g g g g g g g g


were able to research and access different types of information before the int
g g g g g g g g g g g g


ernet! There is a particularly good reason for that: the internet represents an
g g g g g g g g g g g g g


evolution of human civilization comparable only to the invention of writing aro
g g g g g g g g g g g


und 5,000 years ago. Behind this phenomenal change in our lives was the cr
g g g g g g g g g g g g g


eation of the World Wide Web (WWW) just over 30 years ago. Like any devel
g g g g g g g g g g g g g g


oped language, both the internet and the WWW have rules—
g g g g g g g g g


they rely on simple definitions of protocols. These protocols are agreements
g g g g g g g g g g g


on how portions of data are exchanged between every computing device that
g g g g g g g g g g g


gis connected to a basic physical infrastructure provided by governments and
g g g g g g g g g g g


organizations around the world. In the following reading and video resourcesg g g g g g g g g g g


here, you will gain a fundamental understanding about how this remarkable e
g g g g g g g g g g g


volution of our civilization came to be.g g g g g g



In addition to a brief reading that provides a timeline of the history of internet
g g g g g g g g g g g g g g g


and the WWW, a video provides statements from the creator of the WWW, Ti
g g g g g g g g g g g g g
