If a computer has a 4 GB memory limitation and two 512 MB modules are already installed, what is the maximum additional RAM you can add?

2 GB
3 GB
4 GB
1.5 GB

The correct answer is: 3 GB

To determine the maximum additional RAM that can be added, first, it’s essential to recognize the total memory limitation of the computer, which is 4 GB. Currently, two 512 MB RAM modules are installed. To find the total amount of RAM already in use, you can calculate: 512 MB + 512 MB = 1 GB Now, subtract this used memory from the total memory limitation: 4 GB (total limit) - 1 GB (currently installed) = 3 GB This calculation shows that the maximum additional RAM that can be installed without exceeding the 4 GB limit is indeed 3 GB. Understanding this process is crucial, especially in scenarios involving memory configurations, as it helps in effectively upgrading system hardware within specified limitations.
