I'm trying to advance my knowledge of computers to todays standards. I built my own pc recently and used what I guess you can all say is yesterdays standars. My pc is a 1.4Ghz P3 with an IDE drive, etc.

I want to build a new pc soon and I would like to know what and why is there IDE and SATA? What is the difference? What does it mean or stand for?

Any information would be helpful. I assume that a SATA hard drive can only go on a certain motheboard or something?

well that can be a complicated answer but the most brief and easiest way would be to say... ide or PATA is old technology and SATA is the new technology. And yes either your motherboard has to support it or you need to have a seperate card for it. essentially sata is faster than ide and the cables are much smaller and don't block airflow...Also ( at least in theory...haven't tried myself ) sata are hot swap though it's debateable if the motherboard would be able to pick it up correctly or not...
