Shared Internet Connection

What is a router? This is a device that forwards data packets along networks.My housemate told me that we will contribute money to buy a router so that we can have more than one internet connection in the house without increasing monthly bill.I had a doubt if the connection is fast like before.Still we try to have a router.My housemate can use her
laptop now, mine is desktop and the guy is i pod.The connection slow down if we use the internet together.
