In the same spirit, there are sometimes simply problems with the physical cables that connect various types of computerized equipment. Sometimes these physical connections become broken, severed or simply short out. In the case of an electrical short, this can happen when the conductor comes into contact with an outside source that also serves as a conductor. This will reroute the signal and cause networking and/or other electrical problems. In order to correct these types of problems, check to see if the physical connections have been compromised. If so, these can easily be changed, or new wiring can be manufactured with the proper connections by the staff members of the systems department. If nothing appears to be physically disrupted, then cable testers can be utilized to test for other types of electrical and networking problems. These include connection problems, electrical shorts in the cabling, incorrect cable connections and the interference level, in the case of a signal disruption due to diverted conductor paths.
