What term describes a network of millions of interconnected computers?

The term that describes a network of millions of interconnected computers is the Internet. The Internet is a vast global system comprising numerous private, public, academic, business, and government networks linked by a broad array of electronic, wireless, and optical networking technologies. It enables the exchange of data and communication across different devices and platforms.

The Internet functions on a standardized suite of protocols, primarily the Transmission Control Protocol/Internet Protocol (TCP/IP), which allows diverse systems to communicate with one another. It supports various applications and services, including the World Wide Web, email, file sharing, and many others, making it a fundamental infrastructure for information and communication in the modern world.

In contrast, an intranet is a private network used internally within an organization, offering limited access to authorized users. An extranet is an extension of an intranet, providing secure access to specific external users, such as partners or vendors. A database, on the other hand, refers to a structured set of data held in a computer or server, designed for efficient storage and retrieval, and is not a network of interconnected computers.
