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
dataA 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.
