Wi-fi connection (aka 802. 11) uses radio waves to transmit information. The router is actually a small computer whose job it is to connect to other devices and in turn connect them to the outside internet (usually over a wired ethernet connection). Home routers usually connect up to 4 computers with ethernet and more by wi-fi), it must be connected to isp (internet service provider) in order to connect home, which costs $) Cable modem converts signals of your home network (ethernet) to and from a signal that can be carried by cables of the television company.
