Virtual Private server meaning you can have more than 1 inside 1 dedicated server yet it acts as if the dedicated server was yours. It is depends on a dedicated server, but there may be other 4 or 5 VPSs on that same server. With VPS you are basically sharing the resources of a single dedicated between all of the VPSs hosted on it.
So, depending on your needs a VPS may be better, because they are reasonably priced as compared to a dedicated server, or a Dedicated server might be better, because it is completely yours and there are no other root users.
