Which of the following statements are true about volatile memory?Each correct answer represents
a complete solution. Choose all that apply.

A.
Read only memory (ROM) is an example of volatile memory.

B.
The content is stored permanently and even the power supply is switched off.

C.
A volatile storage device is faster in reading and writing data.

D.
It is computer memory that requires power to maintain the stored information.

Explanation:

Volatile memory, also known as volatile storage, is computer memory that requires power to
maintain the stored information, unlike non-volatile memory which does not require a maintained
power supply. It has been less popularly known as temporary memory. Most forms of modern
random access memory (RAM) are volatile storage, including dynamic random access memory
(DRAM) and static random access memory (SRAM). A volatile storage device is faster in reading
and writing data.Answer options B and A are incorrect. Non-volatile memory, nonvolatile memory,
NVM, or non-volatile storage, in the most basic sense, is computer memory that can retain the
stored information even when not powered. Examples of non-volatile memory include read-only
memory, flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy
disks, and magnetic tape), optical discs, and early computer storage methods such as paper tape
and punched cards.
