Find bandwidth comparison charts online at UseWisdom.com, Lageman.com and UTexas.edu. The websites compare bandwidth speeds on different devices, such as cable modems, dial-up modems and Ethernet networks.
Many different factors determine Internet speed, including connection type, traffic congestion, and the quality of connections and equipment. High traffic congestion normally occurs after regular business hours. Outdated equipment slows down the speed of data. In addition, a computer that is farther away from an Internet hub takes longer to receive data from the hub. Ethernet, T3 and fiber connections deliver the highest Internet speeds as of 2015. Dial-up modems offer the lowest speeds.
