A. The reduction in processing speed when multiple applications compete for CPU space.
B. The extra time needed to fetch data from the slower main memory when it is not found in the cache.
C. The financial cost of manufacturing faster cache chips.
D. The permanent loss of data due to system power fluctuations.
Answer: Option B
Solution (By JKSSB Mock Tests)
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.
Explanation:
A page fault occurs when a running program attempts to access a memory page mapped into its virtual address space, but that page is not presently resident in physical RAM.
