Remember to include the amount of memory required to store the Blocks in your calculation. (f) INodeDirectory, consider the same assumptions from INodeFile, and also assume that there are 10 INodeFiles per INodeDirectory. Remember to include the amount of memory required to store the INodeFiles in your calculation. Note that in all of your calculations you should assume a 64-bit CPU architecture and Java 7. Don't forget to consider the padding in your calculation
