If you want to store programs and data permanently on a computer where is it placed?

Data can be placed in a multitude of locations in a computer, but most often it is placed in the hard drive.

However, if a computer has a CD/DVD burner, a floppy disc drive, or a USB thumb drive, then data could be placed on those locations as well, but installed programs typically do not reside on any kind of removable storage device like CD/DVDs, floppy discs, or USB thumb drives.

There is no way to permanently store data on a computer on most storage drives since many can be erased by the user, with the only exception being certain types of CDs and DVDs which can write data on a particular section of the disc once.
