A peripheral device that are used to hold data even when the computer is turned off.

is the part that holds the data

some device outside of the computer to store data

can only use data and instructions in the memory

store data as magnetized particles on a surface (hard drive)

store data on their surface by little pits burnt by a laser into the surface

Also referred to as removal media, is a nonvolatile, removable medium that uses intergrated circuits.

They are the main method used for data storage. It has read/write heads allowing data to be written to or read from the disk surface.
