A computer having 4 GiB of RAM allocates the memory in units of 64 KiB. For b. and c., assume each entry in the linked list contains a 32-bit next pointer, a 32-bit offset, and a 32 bit length is more needed?)

a. How many KiB are needed if a bitmap is required to keep track of free memory?

For this, I have the following:

size of RAM: 1024^3 * 4 = 4.194e+6 KiB

size of each sector: 64 KiB

number of bitmap: 4.194+e6 KiB / 64 KiB = 65532

Size of the bitmap: 65532 bits = 8 KiB

b. If a linked list is used to keep track of free memory, what is the least amount of memory required for the linked list?

c. If a linked list is used to keep track of free memory, what is the largest amount of memory required for the linked list?
