A wireless connection uses what medium?

• A. Wired
• B. Radio signals
• C. Fiber optic
• D. Coaxial

Answer: (B)

Wireless connections rely on radio signals. These are electromagnetic waves that travel through the air, carrying data without a physical conductor. In a wireless link, information is encoded onto these radio waves and transmitted through the surrounding atmosphere or space, which is why you can connect without plugging in a cable. The other options refer to physical cables—coaxial or fiber optic—or to any wired path, which is not how wireless communication works.
