If I buy a new hardrive for my computer, is the hardrive the same thing as a CD ROM that you put the discs in? or is it different. Cause if its the same thingI dont have to buy a new one?
No. A hard drive is a disk that you may connect to your computer either internally or externally. It is not very big, but it holds a lot of information. Just type in "What is a hard drive" on google and browse around. There will be many good results for you to speculate.
