A CAT-5 terminal switch extender uses standard RJ45 connects and CAT-5 cables, but they do not run over a LAN network. In some ways they work like a LAN terminal, but the only difference is that they use CAT-5 grade cables. Most CAT-5 remote setups are done locally, so the computers cannot be accessed through the internet. A KVM extender is a cross between KVM over IP and a standard terminal. Their range is only efficient within a few hundred feet, making it unusable for interstate or intercontinental connections. CAT-5 is a faster and more secure cable compared to LAN, making it the better choice if you can afford it.
