How does a repeater work?

Question

I just place it (repeater) between the router and the destination, right?
I only hook up the power ( hook it to the power outlet), right?
Most of them are like 2 in 1, right( wireless router + repeater) ?
It has another name? when I typed it on yahoo shopping or bestbuy , there were only a few things came up and not all of them were repeaters. Please help me

Answer 1

Yes you just put the repeater between the router and the destination, im not sure about wireless routers being repeaters, i dont think they can be though, id stick to the repeater to be safe.
