Are downloads at the dell support site free?

Hello,

I need to know if the downloads at the dell drivers & downloads site are free or not. Here is the specific url that i'm referring to if needed: http://support.dell.com/support/downloads/driverslist.aspx?os=WW1&catid=-1&dateid=-1&impid=-1&osl=EN&typeid=-1&formatid=-1&servicetag=&SystemID=INSPIRON1545&hidos=WLH&hidlang=en&TabIndex=&scanSupported=False&scanConsent=False

Thank you very much,
Austin
