What is the primary feature of the World Wide Web?

The primary feature of the World Wide Web is that it serves as a network that connects computers worldwide, enabling users to access and share information across the globe. This interconnected structure allows for the transmission of web pages, applications, and various types of data via the internet, making it a fundamental element of digital communication and information exchange.

The World Wide Web is built on protocols such as HTTP and uses browsers to present content that can be accessed by users worldwide, breaking down geographical barriers and democratizing information access. This global connectivity underscores the web's core purpose, which is facilitating interaction and communication through shared resources and information.

In contrast, the other choices highlight aspects that do not accurately capture the essence of the World Wide Web. A private computer network pertains to localized communications and does not embody the worldwide access offered by the web. A platform for social media represents a specific application that uses the web rather than the web itself. Lastly, a service exclusively for governmental use suggests a restricted and non-inclusive use, which does not align with the wide-reaching aim of the World Wide Web.
