The purpose of a storage device to store data software for later use. The
storage device will make some use of physical effect to represent the data.
 CD, DVD, Blu-Ray – a laser burns dark pits into the medium.
 Hard drive and magnetic taps use magnetic domains to represent data
 Flash drive use electric charge to store the data
A primary storage device is the main computer storage device, and a
secondary device is one where you can also store files, but it is not the
main storage you use.
