MIG- is metal inert gas. It means simply a wire feed (the consumable electrode) welder with a inert shielding gas, such as argon or CO2. Meant for more production work, easy to use and get results.
TIG is tungsten inert gas, "An electric torch" so to speak. A torch holder that has a nozzle holding a tungsten electrode(non-consumable), that has a flowing shielding gas such as Argon/CO@(or in rare cases pure Helium,Big $$$$) Meant for precision welding and for nice neat work. Typically really strong.
Edit- I see you have 2 welding related posts, I think you might have to do a little more research, out side this forum on this subject, as there will be some info we wont be able to fully explain to you, in which we will most likely be referring you there any ways.

HAHA...... oh snap....
Didnt see that coming.
Well OP you now have some answers.

Ok, i get it,like i said this is all new to me but very valuable,thanx! You mentioned argon or co2 gas? What is the difference in quality of weld and im guessing that the co2 is cheaper? jim

Aluminum you need pure Argon, Co2 can be for anything steel and other non ferrous materials. You can get into mix gas and that helps alot of weld process, less sparks/spatter. The gas company will have there own mix name but its all the same.
Price wise, typically co2 is cheaper, but you live with the weld quality. Also the type of steel or alloy like different gasses/mixes.
Most of this there is a number of welding tables out there already, just google the material and gas use charts.

As a new welder, you will want to use C25 MIG gas (argon/CO2). That will cover everything you will need for a long time. Buy the largest bottle you can because the small ones cost almost the same as the largest, due to fees, etc. For example, 125 cf bottle is a good size for most hobbiest. Where I get my gas, the difference in a 20 or 40 cf and the 125 cf is less than $10.
MIG wire size is also important. Wire .030 will cover most of what you are likely to need, but I use .023 a lot too.
While MIG is the easiest to learn, you need to be careful because a pretty weld may not be a strong weld. You need to do some destructive testing to gain confidence in your welding ability. It is not simply hot glue for steel.
