What are two sources of electromagnetic interference that can affect data transmissions?

Radio Frequency Interference (RFI): This is a common source of electromagnetic interference. It is caused by sources such as radio transmitters, electric motors, power lines, fluorescent lights, or any device that uses radio frequency energy in its operation. These devices can emit electromagnetic radiation that can interfere with the proper functioning of other electronic devices, including data transmission systems.

Electromagnetic Pulse (EMP): This is a burst of electromagnetic radiation that can result from certain types of high energy explosions, like a nuclear explosion, or from a suddenly fluctuating magnetic field. The rapid change of electromagnetic field can induce currents that can damage or disrupt electronic equipment, including data transmission systems.
