MAH-CET 2026 — Computer PYQ
MAH-CET | Computer | 2026
Cache and main memory will not be able to hold their contents when the power is OFF. They are
Choose the correct answer:
A.
dynamic
(Correct Answer)
B.
static
C.
volatile
D.
non-volatile
Correct Answer:
dynamic
Explanation
The correct option is (c) volatile.
Detailed Explanation
Volatile Memory: This type of computer memory requires electrical power to maintain its data. The moment the power is switched off, all the stored contents are instantly lost. Both Cache memory (made of SRAM) and Main memory (RAM, typically DRAM) are classic examples of volatile memory.
Non-volatile Memory: This type of memory retains its saved data even if the power is turned off (e.g., ROM, Hard Drives, Flash drives).
Static and Dynamic: These terms describe how volatile memory maintains its data while power is on. Static RAM (SRAM) uses flip-flops and doesn't need refreshing, whereas Dynamic RAM (DRAM) uses capacitors that must be constantly refreshed. However, both will lose data when power is completely removed.
