Answer» primary memory is not capable to store data it stores data only for some time so we have to use secondary memory like hard disk etc.to store data. All secondary storage devices which are capable of storing high volume data is referred to secondary memory. It\'s slower than primary memory. However, it can save a substantial amount of data, in the range of gigabytes to terabytes. This memory is also called backup storage or mass storage media. |
