What is the typical capacity of a DVD-R DL (dual layer) disc? MCQ with Answer and Explanation

Digital cameras use removable flash memory cards like SD cards for storing photos and videos.

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.

Explanation:
SRAM uses flip-flop circuits to store each bit, while DRAM uses a capacitor and a transistor. SRAM is faster and does not need refreshing, but is more expensive. Both are volatile.
