Assume you have a computer that contains 2GB of memory. It contains four memory slots. Each slot can contain 128 MB, 256 MB, 512MB, 1 GB, or 2GB memory modules. Currently, each slot contains a 512MB memory module. What combinations of memory modules will satisfy your memory upgrade to 8GB? Which of these combinations is the least expensive.
4 slots with 2GB each. Since this is the only combination that will give 8GB, the last inquiry is a moot point.
What combinations of memory modules will satisfy your memory upgrade to 8GB? Which of these combinations is the least expensive.
To calculate the combinations for memory upgrade to 8GB, we need to find all possible combinations of memory modules that add up to 8GB.
First, let's convert 8GB into megabytes (1GB = 1024MB):
8GB * 1024MB/GB = 8192MB
Now, we will compare the memory modules currently installed in the computer to the available memory module options.
The current memory modules are: 512MB in each slot.
The available memory module options are: 128MB, 256MB, 512MB, 1GB, and 2GB.
To find the combinations, we will iterate through each slot and try out different memory module configurations while keeping track of the total memory size.
Here is one possible combination of memory modules:
Slot 1: 2GB (2048MB)
Slot 2: 2GB (2048MB)
Slot 3: 2GB (2048MB)
Slot 4: 2GB (2048MB)
Total memory size: 2048MB + 2048MB + 2048MB + 2048MB = 8192MB (8GB)
This combination fulfills the requirement of upgrading the memory to 8GB.
Now, let's calculate the cost of this combination. We'll assume each memory module has a certain dollar value associated with it.
Cost of each memory module:
128MB: $10
256MB: $20
512MB: $30
1GB: $50
2GB: $80
The cost of the combination above would be:
Slot 1: 2GB ($80)
Slot 2: 2GB ($80)
Slot 3: 2GB ($80)
Slot 4: 2GB ($80)
Total cost: $80 + $80 + $80 + $80 = $320
So, the least expensive combination to upgrade the memory to 8GB is using four 2GB memory modules, which has a total cost of $320.
