DRAM is a Volatile random-access memory (VRAM).

Volatile random-access memory (VRAM) is random-access memory that retains its information when power is turned on.

Examples of volatile memory are primary storage (typically dynamic RAM, DRAM), and fast CPU cache memory (typically static RAM, SRAM, which is fast but energy-consuming and offer lower memory capacity per area unit than DRAM).

Non-volatile random-access memory (NVRAM) is random-access memory that retains its information when power is turned off.

Examples of non-volatile memory are flash memory (used as secondary memory) and ROM, PROM, EPROM and EEPROM memory (used for storing firmware such as BIOS).

The interviewer wants to know that you don't just jump into a solution without knowing the problem in detail. You want to study the problem by determining the cause of the problem, what the problem is, and what the possible solutions are. You then decide on a solution.

Following steps for problem-solving and decision-making can be very helpful.

- Define the problem to be solved and decision to be made.
- Gather the necessary information.
- List all possible choices.
- Consider possible outcomes for each choice.
- Check out how you feel about each of the choices.
- Relate the choices to your values and priorities.
- From the possible alternatives, choose one.
- Commit yourself to your chosen decision and disregard the others. Concentrate your energies   in one direction. Once we made our decision, we must focus all our work on that itself.
- Take steps to turn your decision into positive action.
- Evaluate your progress from time to time. Change your decision if necessary.
