Cabling is crucial to every network. Correct use of cables helps build a reliable, high performance network; wrong use of cables can doom a network to performance problems, outages, and constant troubleshooting. As a result everyone who plans, builds, and maintains networks- PC technicians, cabling technicians, and network consultants needs to know all about various types of cables- from those used to network desktops to hubs and switches up to those used by major telecommunications carriers.
