The Force.com API comes in two 'flavors', which are functionally equivalent and share the same operations, but differ in how developers interact with them. The first, referred to as the Enterprise WSDL, is a strongly typed version of the API, meaning that an object in force.com will have an equivalent object in Java, .NET or whatever environment is accessing the API. In this model, where your code is compiled against a particular schema, has the benefits of generally being easier to code in (as you don't need to deal with any underlying XML structures), and safer in the sense that data and schema dependencies are resolved at compile time, not at runtime.
The downside of that strongly typed model is that it only works on a single force.com account's schema, as it is bound to all of the unique objects and fields that exist in that account's data model. So what if you are creating a solution that you want to be able to work across multiple accounts from different customers? In that case, you need a weakly typed representation of the data, which is precisely what the Partner WSDL provides. In this model, the developer is responsible for marshaling data in the correct object representation (which typically involves diving into the XML), but the developer is freed from being dependent on any particular data model or force.com account.
Put simply, if you are a company using the API exclusively on your own account, you'll typically want the Enterprise WSDL, and if you are an ISV using the API across many accounts, you'll typically want the Partner WSDL.
