they're not the same, but usually a consiquence of the same process, in certain renderers.

basically, GI is the distribution of bounced environmental and indirect light, whereas radiosity is the bounced 'heat' source from a materials surface or colour which effects it's immediate surroundings with a 'colour bleed'.

as i say, most renderers render both together, but a few you can render either or.
