What action allows a laptop to connect to the Internet using a cellular network?

Enable DHCP
Install Wi-Fi drivers
Install a cellular USB adapter in an open port
Use a mobile hotspot

The correct answer is: Install a cellular USB adapter in an open port

Connecting a laptop to the Internet using a cellular network typically involves utilizing a cellular USB adapter. This device is designed to provide mobile broadband access, essentially allowing the laptop to communicate with cellular towers, similar to how a smartphone connects to the Internet through its data plan. When you install a cellular USB adapter, it acts as a bridge between the laptop and the cellular network. This method is particularly useful when Wi-Fi networks are unavailable or if fast mobile data speeds are needed. The laptop recognizes the connected USB adapter, and after appropriate drivers are installed, it can access the Internet via the cellular network established by the adapter. Other options focus on different types of network setups that do not directly pertain to using cellular connectivity. For instance, enabling DHCP is related to configuring network addresses dynamically, which is more relevant for local area networks rather than cellular connections. Installing Wi-Fi drivers facilitates connections to Wi-Fi networks, not cellular ones, while using a mobile hotspot involves sharing an Internet connection from a smartphone or dedicated hotspot device, which is a different approach to accessing the cellular network.
