Option 4 : All of the options

Option 4 is correct:

Definitions:

A memory that can retain the data even if the memory is not connected with the power supply is known as non-volatile memory.

A memory that loses data if the power supply is disconnected is called volatile memory.

 

  • The flash memory belongs to the non-volatile memory group as it can store data for a permanent time. Examples of flash memory are BIOS chips.
  • ROM stands for read-only memory, and it is permanent storage where once the stored is stored then it cannot be updated or erased. An example of ROM is a controller chip used in electronic devices that defines its functioning.
  • Hard Drive is a storage memory that is used as a secondary memory in computers. It stores data for a permanent time. But the data can be altered and erased as per the user requirement.
