The Internet is a global network that connects billions of computers, servers, smartphones, and other devices, allowing them to communicate and share information. It gives people around the world instant access to websites, email, online applications, streaming services, and countless other digital resources.

This worldwide network operates using standardized communication protocols, such as TCP/IP, which enable different devices and networks to communicate seamlessly regardless of their location.

How Does the Internet Work?

Every time you visit a website, send an email, or stream a video, your device exchanges data with servers over the Internet. This process relies on a global infrastructure of networks and standardized communication protocols that ensure information is delivered quickly, accurately, and securely.

Brief history

The Internet traces its origins to ARPANET, a computer network developed by the United States Department of Defense in 1969 to enable communication between research institutions.

In 1989, the invention of the World Wide Web (WWW) transformed the Internet by making information easily accessible through web browsers. This innovation paved the way for the modern Internet, making it possible for businesses, organizations, and individuals to publish and access information online.
