Assume you now have 1kB of memory, i.e. the memory address space runs from 0 to 1023. The starting address of the first word is 0, the second word is 4, the third word is 8, and so on.

The last word comprising 4 bytes resides in addresses 1020, 1021, 1022, 1023. Thus, the last word starts at 1020, which is a multiple of 4.

Now assume the same 1kB of memory but now, word size is 64 bits. The starting address of the first word is 0, the
second,
third, and
last
word starts at?
