If several programs or apps are running simultaneously, your computer might use up its available _____.

• A. RAM
• B. CPU
• C. Network bandwidth
• D. Disk space

Answer: (A)

When several programs are running, the system needs fast, temporary storage to hold the data and instructions those programs are actively using. That fast storage is RAM. If RAM fills up, the operating system moves less-used data to slower storage on the disk (virtual memory) to free space, which makes everything slower because accessing disk is much slower than RAM. This scenario is about memory capacity, not long-term storage, so RAM is the limiting factor. CPU handles processing, but it isn’t what gets “used up” in the sense described here, and network bandwidth or disk space aren’t the immediate constraints when multiple apps are open unless those specific resources are being heavily used.
