It uses a hard drive, resembling most lap tops. But if you want you can buy external firm drives or memory cards to hold all your extra stuff.
most likly DDR2. to find out for sure, click start and later right click on my computer, go to properties, and afterwards click the general tab; it should recount you your computer's specs there. and for computer [parts, check out tigerdirect.com or newegg.com. if you anticipate storage, that would be a harddrive, where you amass your files and stuff to. you can get those for cheap at those sites as very well, as well as external ones that you can pass around separately from your laptop.
