Connections for computer systems can require a number of components from modems and routers to power over Ethernet. Wired networks require devices be tethered to a router. The most common wired networks use cables connected to an Ethernet port on the network router and the opposite end of the cable connected to a computer or other device. The world of wireless in networking is making this once time-consuming task much easier. With a wireless network, devices stay connected to the network but do not need to be tethered by any wire. Access points amplify Wi-Fi signals, so a device can be far from the router, but still connected to the network.
