Computers - General Knowledge Questions

they are more economical

they do not require boosting

they generate strong magnetic fields

they do not generate magnetic fields

Correct Answer : Option (D) - they do not generate magnetic fields

Optical fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Besides, there are no radiated magnetic fields around optical fibers; the electromagnetic fields are confined within the fiber. Since fiber optics do not radiate electromagnetic energy, emissions cannot be intercepted.
