You add 512 MB of RAM to a laptop computer that already has 512 MB of RAM. The laptop computer is configured for 64 MB of shared video memory. The user runs graphic intensive applications.
How much memory is available for the operating system and applications?
1. 1088 MB
2. >>960 MB
3. 896 MB
4. 1024 MB
Explanation : When a laptop is configured to use shared video memory, a portion of main memory is used by the video adapter. If graphic-intensive applications are used, you should subtract the amount of shared video memory from the amount of main memory to determine how much Random Access Memory (RAM) is available for applications and the operating system to use. In this case, that is 1024-64 = 960 MB.
You will not have 1024 MB of RAM available because 64 MB of memory will be used by the video adapter. You would have 1024 MB of RAM available if the laptop had dedicated video memory.
You do not need to subtract the video memory from each memory chip. You add the total amount of RAM and subtract the amount of shared video memory to obtain the total available memory.
You do not add the amount of shared memory to the total available.
