what is the dofference between a macbook pro and macbook air

Depends on the particular models in question. However, the MacBook Air has always been extremely thin and had more limited ports available than the MacBook Pros of the same era. It's usually been of somewhat lower performance. The original MBA used a different Intel Core 2 processor than the corresponding MacBook Pro. It was geared towards better battery life at the expense of some performance.

Generally the Air is less powerful, has fewer ports and cost less.

But, you can get to the point with added upgrades to the Air you approach the Pro's attributes. With the exception of number of ports.
