A computer has 16GB of RAM. It typically needs to support 100 processes, each of which require an average of 100MB. Will this computer benefit from a Virtual Memory system? Choose the correct option and reasoning below.
Explanation
Option 3: Yes, since Virtual Memory provides protection across different processes
Solution & Explanation
To understand why Option 3 is correct, let's break down the mathematical data given in the problem and look at the core functions of a Virtual Memory system.
1. Mathematical Analysis of Memory Size
Total Available Physical Memory (RAM): 16 GB
Number of Processes: 100
Memory required per process: 100 MB
Total Required Memory:
100×100 MB=10,000 MB≈10 GB
Since the total memory required (10 GB) is strictly less than the available RAM (16 GB), the computer does not strictly need virtual memory for expanding its physical storage capacity (precluding the common "out of memory" scenario).
