ITPEC IP April 2019 Question 11
ITPEC IP April 2019 — Question 11 of 100
Flash memory is non-volatile, so it retains stored data even when power is removed. It can also be erased and rewritten electrically, which is why it is widely used in memory cards, USB drives, and solid-state drives.
Answer (b)
Why not others:
- (a) describes write-once storage, whereas flash memory can be rewritten
- (c) is false because flash memory can be made compact and is commonly used in digital cameras
- (d) describes optical media such as CDs or DVDs, not semiconductor memory
Key rule: Non-volatile semiconductor memory retains data without a continuous power supply.
