A network cable is used to connect a computer to a network. This can be a range of setups such as a broadband router feeding a single computer, two computers connected directly to each other, or a multiple number of computers and a network printer all connected to a server or router. RJ45 is the plug type. Compared to the lower CAT cables, CAT 7 provides increased bandwidth, up to 10GbE. Note that there are two configurations of cables, Straight and X-Over (crossover). A X-Over cable is only used when connecting two computers directly to each other, or when connecting a computer directly to a peripheral for setup/configuration purposes.
