Which type of memory uses capacitors to store data and needs periodic refreshing?
A. DRAM
B. SRAM
C. Flash memory
D. ROM
Answer: Option A
Solution (By JKSSB Mock Tests)
DRAM (Dynamic RAM) uses capacitors to store bits; they leak charge and must be refreshed periodically. SRAM uses flip-flops and does not need refreshing.
Explanation:
Each generation of DDR memory features a physical alignment notch carved into a unique position along the pin edge to prevent incompatible physical installation.
Explanation:
Virtual memory is a memory management technique that uses secondary storage (like an HDD or SSD) to simulate additional RAM, allowing programs to run even if they exceed physical memory capacity.
