The correct option that best describes what the Internet is, out of the given choices, is: A network of computers.

Explanation:
The Internet is a global network of computers that are connected and can communicate with each other. These computers can be located anywhere in the world and are connected through various communication technologies such as wires, fiber-optic cables, or wireless connections. The Internet allows users to share information, access websites, send emails, connect with other people, and perform various online activities. While a web browser is a software application that allows users to access information on the Internet, and a collection of websites is a part of what is available on the Internet, it is the network of computers that makes it all possible. A folder that stores files is more of a local storage concept on a single computer and is not directly related to the definition of the Internet.
