I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

basically an interface is like  contract...its tells the implementing class what methods can be used, but not HOW to use them..the implemenation of those methods are left up to the class.  Also interfaces can allow for multiple inheritence, whereas a class can only inherit one other class.  You can use interfaces when classes may implement similar methods differently.  this is a very simple explanation...I would suggest reading more about it.  Here are a few articles with some examples.
