Which term refers to interference caused by devices like cordless phones and microwave ovens on the network?

• A. Radio Frequency Interference (RFI)
• B. QoS
• C. Privacy
• D. Protocol

Answer: (A)

Radio frequency interference describes the unwanted energy from other devices that disrupts wireless communications. Cordless phones and microwave ovens emit radio waves in the same bands that networks use (such as the 2.4 GHz ISM band), creating noise on the channel. This interference degrades signal quality, increases errors, and causes retransmissions, leading to slower or unstable connections. QoS is about prioritizing traffic, not interference; Privacy concerns confidentiality; and Protocol is the set of rules for how devices communicate. So the term that captures this interference is radio frequency interference.
