The primary difference between RAM and secondary storage devices is
a.
RAM accepts input; secondary storage devices do not.
b.
RAM is permanent and secondary storage is temporary
c.
RAM is volatile and loses its contents when power is turned off, while secondary storage devices retain their contents even when power is turned off.
The correct answer is c. RAM (Random Access Memory) is a volatile form of memory that is used to temporarily store data that the computer is actively using. When the power is turned off, the data stored in RAM is lost. Secondary storage devices, such as hard disk drives and solid-state drives, are non-volatile and retain their contents even when power is turned off. They are used to store data that needs to be kept even when the computer is not running, such as programs, documents, and media files.
