The secondary memory is all other memory outside of the main memory that the computer accesses. Secondary memory is used for long term storage and gets physically changed when files are saved or deleted. Because of this change it is slower than main memory (although still very fast). The secondary memory is much larger than the main memory and usually only gets changed when a user changes the information, such as saving or deleting. Common secondary memory devices are the hard drive, floppy disks, CD-ROMs, USB storage devices, and flash drives. These things hold the software (OS and Apps) that the main memory will access.
