Generally speaking, a limiter is a compressor applied to a channel which has a high threshold and high ratio. They are designed to compress peaks which already high level to stop them hitting 0 and clipping, as such they don't usually require much if any make-up gain.
Maximizers tend to do the job of reducing the dynamic range more significantly. They have been used to literally maximize how loud the track/channel can possibly be without clipping, much to the majority of the professional industry's dismay. They also tend to have a 'look forward' option to assess the audio just before it actually needs to be processed, that way it can make the compression less noticeable.
Hope this is helpful
