What is the best description of the Internet?

The best description of the Internet is a global network of interconnected computers. This definition captures the fundamental nature of the Internet, which is based on a vast infrastructure that enables computers and devices around the world to communicate with one another. This interconnectedness allows for the transfer of data and information across various networks, facilitating a wide range of activities, from browsing websites and sending emails to streaming videos and participating in online gaming.

In contrast, social media sites represent only a small component of the Internet, as they are platforms for interaction and content sharing rather than the overarching network itself. An online marketplace is a specific application of the Internet that focuses on buying and selling goods and services, while a database of websites describes a curated collection of online resources but does not encompass the scope of connectivity that defines the Internet. Thus, the most accurate and comprehensive description is that of a global network of interconnected computers.
