How, Why, What, Where, and who uses a router?

The most frequent routers are the ones that are small, specifically used in homes and small offices that simply transfer data from one network to another. There is of course some more developed type of routers used by bigger organizations, used to connect more than two networks. Any person who uses a computer with internet service can use a router if he is aware of how to use it. But he will need to ask for the help of an IT specialist in the beginning, to connect the router to the concerned networks. You have to make sure than both computers that need to be connected are supplied with LAN cards. The router should have two Ethernet ports so that you could be able to connect it to both networks.
