Signal fading is a decline in transmission strength. Fading can occur when a signal is transmitted by microwaves. Under certain conditions, the signal picked up by the receiving unit can be quite weak. A weak signal is more susceptible to transmission noise and error. Signal...

Information validity implies data elements represent real conditions, rules or relationships rather than physical object characteristics. IT hardware validity checks are preventive and/or detective control measures that should be implemented to ensure appropriate data processing. There are three...
