Which technology is applied in writing data onto a CD-RW disc to allow repeated overwriting?
A. Phase-change alloy material
B. Dye ablation
C. Floating gate transistor charging
D. Magnetic field reversal
Answer: Option A
Solution (By JKSSB Mock Tests)
CD-RW discs use a phase-change material that can transition between crystalline (reflective) and amorphous (absorbent) states via laser heating to clear or write data.
Explanation:
When the CPU looks for data in the cache and fails to find it (a cache miss), it suffers a time delay penalty because it must fetch that data from the slower system RAM.
