   What is secondary memory?

   • Secondary memory is a type of computer memory that is used to store data and programs that can be accessed or retrieved even after the computer is turned off. Unlike primary memory, which is volatile and temporary, secondary memory is non-volatile and can store data and programs for extended periods of time.

   How is secondary memory accessed?

   • Secondary memory is not accessed directly by the Central Processing Unit (CPU). Instead, data accessed from a secondary memory is first loaded into Random Access Memory (RAM) and is then sent to the Processing Unit. RAM provides a much faster-accessing speed to data than secondary memory.

   Why do we need secondary memory?

   • The storage capacity of processor memory, also known as primary memory, is very low and volatile, in which the stored data is destroyed as soon as the computer is turned off. In such a situation, if we have to store a large amount of data or program permanently, then we need secondary memory.
