Decreasing the RAM of a computer typically leads to which of the following outcomes?
Choose the correct answer:
A.
Virtual memory increases
B.
Page faults increases
(Correct Answer)
C.
Page faults decreases
D.
Segmentation faults occur
Correct Answer:
Page faults increases
Explanation
Main Outcome
RAM↓⟹Page Faults↑
Mathematical Reason
Jab physical memory (RAM) kam hoti hai, toh Operating System ko zyada pages ko Disk par swap karna padta hai. Iska relation niche di gayi equation se hai:
p=Total Memory ReferencesTotal Page Faults
Agar available frames (f) kam honge, toh miss hone ke chances (p) badh jayenge:
If f→min, then p→1
Logical Summary
Primary Effect:Page faults increase kyunki required data RAM mein nahi milta.
Secondary Effect:Thrashing shuru ho jati hai agar RAM working set se choti ho jaye:
\sum \text{Working Set Size} > \text{Total RAM}
