It's hard to tell what software Dell included in your model. As rgd1101 suggested check your manual. I have a Dell Inspiron N5110 at home so I could check tonight I think it came with a pre-installed software simply called "Dell Webcam" so check if you have this. But nevertheless the drivers should be pre-installed so any software you will install that requires a webcam it should be automatically supported. For example, if you install Skype it will automatically detect and support your webcam if your drivers are installed.
