What are the similarities and differences between competitive and non-competitive inhibition within enzymes?

Competitive inhibition occurs when the substrate and inhibitor molecule are similar in shape and size and therefor compete to bind in the enzymes active site, non-competitive inhibition however is when the inhibitor molecule binds to an alternate (allosteric) site and this binding causes a change in shape of the active site which means the substrate can no longer bind and react.
