What is the most widely used communication device, which is now built in to run Wi‑Fi and communicate widely?

• A. Router
• B. Switch
• C. Network card
• D. Modem

Answer: (D)

The main idea here is the device that provides the connection to the broader internet. A modem serves as the bridge between your home network and your internet service provider’s network. It modulates and demodulates signals so your devices can communicate with the wider internet, which makes it the most widely used piece of equipment for internet access. As internet usage evolved, many modems began to include built‑in wireless capabilities, effectively becoming a gateway that both connects you to the internet and distributes Wi‑Fi throughout your home. That combination—internet access plus wireless distribution—is why the modem is described as now being built in to run Wi‑Fi and communicate widely. A router, while essential for sharing a single internet connection among multiple devices and providing Wi‑Fi, is typically used after the modem to manage local traffic. A switch simply expands wired connections, and a network card is a personal device connection point. The modem remains the core entry point to the internet, and when combined with Wi‑Fi, it fulfills the described role.
