1969: The First Step — ARPANET
The Internet started as a research network.
ARPANET
Funded by ARPA in the United States
Connected universities and research centers
Used packet switching
Started with only 4 connected computers
FACT
First ARPANET message was sent in 1969.

The Main Breakthrough: TCP/IP
The rules that let different networks talk to each other.
Without common rules, networks cannot communicate.
Network A
TCP/IP
Network B
Vint Cerf and Bob Kahn helped design TCP/IP.
January 1, 1983 is often called the “birthday” of the modern Internet.
FACT
TCP/IP makes different networks work as one system.

Internet
World Wide Web
The infrastructure:
networks, cables, routers, satellites,
servers.
A service on the Internet:
websites, links, browsers, HTML pages.
FACT

Cyberattacks
Fake information
Privacy
Addiction
Passwords and accounts can
be stolen.
Not everything online is true.
