converting?

[lman]

Instead of guessing about stuff like this, i look to this forum to get my answers. My closest friends were considering splitting the cost for wi-fi in my house (its like 8 of them so split it isn't too much per person).

What i was wondering was if any of the products apple sold simple did the following:

plug it into the wall of the internet outlet in your room and instead of it connecting to a computer to supply the internet, it would make the room wifi. Essentially, internet would be brought to my room in a wired format and then plug something into the outlet to make it wi-fi in my room?

I know their is the base station and the extender and would either of these be able to do that?
