Anyone that uses the web or other internet technologies can benefit from learning at least the very basics of networking, for example, the difference between a telephone cable and a Cat5 ethernet cable and the places they plug into on the back of your computer. \n\nKnowing the difference between public and private networks, how data travels from one computer to another, and how to troubleshoot problems can save you money and frustration, but for many people it's easier to pay someone like me $80 an hour to fix it for them (fast).\n\nIf you work in IT or use networks on a regular basis, it would be very beneficial to study up on TCP/IP and Ethernet basics. Once you understand how things work it makes it much easier to figure out why it's not doing what you want it to do.\n\nHere's a good quick tutorial on TCP/IP:\nhttp://www.w3schools.com/tcpip/default.asp
