Internet: The Globally Connected World

History and Development

The internet, a vast global network connecting billions of devices worldwide, has a fascinating history. From its early beginnings with ARPANET in the 1960s, a research project of the US Department of Defense, to the explosion of the World Wide Web in the 1990s, the internet has undergone a dramatic transformation. From a tool primarily serving research and military purposes, the internet has quickly become an indispensable part of the lives of billions of people globally.

Underlying Technology

The internet operates on a complex set of protocols and technologies. TCP/IP is the main protocol enabling data transmission between computers. DNS (Domain Name System) translates complex IP addresses into more memorable domain names like google.com. HTTP and HTTPS are protocols for data transmission on the web, ensuring security and data protection.
