ITPEC IP October 2021 Question 13
ITPEC IP October 2021 — Question 13 of 100
DRAM and SRAM are volatile, so items (i) and (iii) are correct. Both store bits using electrical states that disappear when power is removed. ROM retains its contents without power, and an SSD uses non-volatile flash memory.
Answer (b)
Why not others:
- combinations containing ROM or SSD incorrectly include non-volatile storage
- a combination omitting either DRAM or SRAM misses a volatile memory type
Key rule: Volatile memory loses stored data when power is removed; both main-memory DRAM and cache-oriented SRAM are volatile.
