•AMD Phenom™ II P650 Dual-Core Processor (2.8GHz) is this good for a laptop with 4gb memory & 500gb hardrive?

I have no idea what a core processor is! someone help explain this to me, and if this is a good laptop for downloading music and saving music, but not like a boat load of music, as well as pictures, like from the webcam and such. As well as enough memory to store papers for college.
