Which of the following is a type of memory that is used for storing data in an e-book reader? MCQ with Answer and Explanation

Explanation:
1x speed for Blu-ray is defined as 36 MB/s (or 36 Mbps? Actually, it's 36 Mbit/s? Wait: 1x Blu-ray is 36 Mbps (4.5 MB/s). Let's check: 1x DVD is 11.08 Mbps (1.32 MB/s), 1x CD is 150 KB/s. Blu-ray 1x is 36 Mbps = 4.5 MB/s. But common speeds are faster. Let me verify: Actually, 1x Blu-ray = 36 Mbit/s (4.5 MB/s). Some sources say 36 Mbit/s = 4.5 MB/s. So option A (4.5 MB/s) is correct. However, I've also seen 1x Blu-ray = 36 MB/s? Let's recall: Blu-ray standard defines 1x at 36 Mbps (megabits per second). So 4.5 MB/s. So correct answer is A: 4.5 MB/s.

Explanation:
CMOS RAM (often powered by a battery) stores BIOS settings such as date, time, and hardware configuration. It is non-volatile but small.

Explanation:
Defragmentation is a utility process that rearranges fragmented data files on a mechanical hard drive so their constituent pieces are stored in contiguous sectors, optimizing read speeds.
