carbs vs throttle bodys

I have bugger all knowledge when it comes to engine related things and have been wondering:

whats the difference between carbs and throttle bodys?
also, what are the benefits if any of using throttle bodys over a carb? :dontknow:

throttle bodies are for injection engines

carbs are for ummn… carb engines!? lol  

But yea I think thats it

Throttle bodies can have a greater airflow than a cabr (you'd need a massive carb to flow as much as you get through a TB), and because they have injectors you can more accurately control the fuelling which makes tuning easy. Carbs are nice and simple but fuel injection has wiped them out for good reason
