A wireless modem is a device that allows PCs to connect to a wireless network and access the Internet through an ISP, commonly including USB sticks. What is this device called?

• A. Wireless bridge
• B. Dipole antenna
• C. Wireless modem
• D. Bluetooth dongle

Answer: (C)

The essential idea here is identifying the device that connects your local network to your Internet Service Provider. A wireless modem is the piece of hardware that terminates the ISP connection and, when equipped for wireless, lets devices share that Internet access over Wi‑Fi. USB sticks mentioned are a common form of mobile broadband modems that plug into a computer to provide Internet access via a cellular network, which fits the description perfectly. Why this fits over the others: a wireless bridge connects two networks but isn’t the endpoint that talks to the ISP for Internet access; a dipole antenna is just an RF radiator used to improve signal, not to provide Internet connectivity; a Bluetooth dongle adds Bluetooth for short-range device communication, not Internet access.
