why do we need routers and in what kind of a location routers are needed the most?

Your Answer

You need an inexpensive device called a router. This is basically a box that goes between your DSL or cable modem and all of your Internet devices (computers, HDTV, and so on). The router shares the Internet signal between the multiple devices. ... Your ISP provides you with one, allowing one device to access the Internet.
