Why do people use Routers??
Every device on the Internet needs a unique IP address. Your ISP
provides you with one, allowing one device to access the Internet.
A router will access the Internet through that IP address, then
provide local IP addresses--not visible on the Internet--for the
PCs and other devices connected to it. This allows you to access
the Internet from multiple computers through one connection. Every
