The Internet is a vast global network that connects billions of computers and other devices, enabling them to communicate and share information. It's often described as a "network of networks" because it interlinks smaller networks from around the world, including private, public, academic, business, and government networks¹².

It supports a wide range of services, such as email, social media, file sharing, and the World Wide Web, which is a system of interlinked hypertext documents accessed via the Internet¹. With the Internet, you can access almost any information, communicate with anyone else in the world, and perform many other activities online³.

The Internet's origins date back to research in the 1960s, but it became more widely known to the public in the early 1990s. Today, it's integral to many aspects of life, including communication, education, commerce, and entertainment¹²..
