Marsha can’t find anything wrong with her computer, but there seems to be a disruption taking place that is causing data corruption. Where would this disruption come from?
Explanation
Answer: B - Cabling can cause disruptions that lead to data corruption. When cabling problems occur, the entire network can experience disruption. There are three major problems that can cause disruption. First, noise on a line is usually caused by surround devices or by characteristics of the wiring’s environment. Noise can be caused by motors, computers, copy machines, fluorescent lighting, etc. These interferences can combine with the data being transmitted over the cable and distort the signal. Next, attenuation is the loss of signal strength as it travels. The longer the cable, the more attenuation is introduced, which causes the signal carrying the data to deteriorate. Once data travels over a certain distance, the resistance of electron flow aggregates and destroys the integrity of the signal. Last, crosstalk occurs when electrical signals of one wire spill over to another wire. When different electrical signals mix, their integrity degrades and data corruption can occur.
