Which term describes signals caused by devices such as cordless phones and microwave ovens that interfere with the network?

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

Answer: (A)

Radio frequency interference describes signals caused by devices such as cordless phones and microwave ovens that interfere with the network. These devices emit electromagnetic energy in radio frequency bands used by wireless networks, which can introduce noise and disrupt transmission, leading to slower speeds or dropped connections. This is a specific type of interference focused on RF energy. Ransomware is malicious software that holds data hostage, QoS is about prioritizing certain traffic to improve performance, and privacy concerns protecting confidential information—none of these describe interference from household devices.
