So a "crossover" cable is a special type of Ethernet CAT5 cable right? It is used often to connect to computers to share files, internet, etc. So supposedly it looks just like any other ethernet cable. If I have an ethernet cable, how do I tell if it's a crossover or not? i have the following cable: CAT5 patch cable to TIA/EIA 568A LL84201 CSA Type CMG FT4 Copartner that's not a crossover is it?
