An Internet connection is a means of linking a device, such as a computer or smartphone, to the World Wide Web. This connection allows users to access online content, communicate with others, and use various services. There are different types of connections, including Wi-Fi, fiber optic, and mobile data, each offering varying speeds and reliability. To establish an Internet connection, users typically need a modem and a router. The modem connects to an Internet Service Provider (ISP), which provides access to the Internet. The router then distributes this connection to multiple devices, enabling them to go online simultaneously.
