What does RF stand for?

• A. Radio Frequency
• B. Read-only File
• C. Rapid Function
• D. Registered Jack

Answer: (A)

RF stands for Radio Frequency. It refers to the portion of the electromagnetic spectrum used to carry wireless signals, describing how fast the signal oscillates, measured in hertz. RF is the basis for many wireless technologies you encounter, like Wi‑Fi, Bluetooth, cellular, and radio broadcasting, where different frequencies affect range and data rates. That’s why Radio Frequency is the correct interpretation of RF. The other options point to unrelated terms—Read-only Memory (not Read-only File), Rapid Function (not a standard IT term), and Registered Jack ( RJ, a type of connector)—so they don’t describe what RF stands for.
