Which of the following components helps connect different devices to the internet?

The modem is the device that connects different devices to the internet. It serves as a bridge between your local network and your Internet Service Provider (ISP). When using a modem, data from the internet can be received and sent out, allowing computers, smartphones, and other devices to access online services and information.

While components like a mouse, monitor, and printer are essential for user interaction and output, they do not facilitate the connection to the internet. The mouse is an input device for navigating, the monitor displays output from the computer, and the printer produces hard copies of digital documents. The modem specifically allows devices within a network to communicate with external networks, making it a critical component for internet access.
