![]() ![]() CAT5e is certified for gigabit support, but CAT5 cabling works as well, just over shorter distances. And while connecting two machines is one practice of using a cross-over cable, another use is to expand a network by connecting another network switch, thus giving you multiple ports. The cable reverses the pins so that the output on one computer is sent to the input of another. With a cross-over cable, users can connect two devices directly without the need for a router in the middle. That router takes all the bits sent out by the computer and relays them onto additional devices in the network or out to the broader internet. ![]() In an Ethernet networking scenario, such as a home with multiple PCs that are wired, the computers need to connect to a principal router. A strong network connection goes for 100 m or more at gigabit speeds. While you can opt to go wireless, those types of connections will typically be slower and are vulnerable to interference. The fastest way to connect PCs together, to a router or central switch, is through Ethernet cabling, a standard that’s been in networking installation for years. ![]()
