Detailed explanation-2: -ANSWER: The “VOLATILE” feature is Unsuitable for the ram for “PERSISTENT STORAGE”. EXPLANATION: RAM stands for “RANDOM-ACCESS MEMORY”; it is useful to obtain the information in the short term of period.

Detailed explanation-3: -It is much faster to read from and write to than other kinds of storage, such as a hard disk drive (HDD), solid-state drive (SSD) or optical drive. Random Access Memory is volatile. That means data is retained in RAM as long as the computer is on, but it is lost when the computer is turned off.

Detailed explanation-4: -NVRAM. Nonvolatile random-access memory (NVRAM) is random-access memory that retains its information even if there is no power. If power is lost before the data is written to disk, you don’t lose the data because it can be recovered from NVRAM. NVRAM uses battery backup to keep data persistent.
