conda is the package manager.
Anaconda is a set of about a hundred packages including conda, numpy, scipy, ipython notebook, and so on.
You installed Miniconda, which is a smaller alternative to Anaconda that is just conda and its dependencies
(as opposed to Anaconda, which is conda and a bunch of other packages like numpy, scipy, ipython notebook, etc.).
Once you have Miniconda, you can easily install Anaconda into it with conda install anaconda.
