This is for Computer Architecture. Please the following questions, (for number 9 there is no need for mapping just answering the questions). Thank you.

8). How many bits are in an address, if the main memory holds 256k words?

9). A MM has 2^10 words, cache has 32 blocks, and each block has 8 words.
