hey,

i have a few questions that im working on in preperation for my finals. if some1 could please show me how to do it or atleast guide me in the right direction, it would be really appreciated.

Q. In a 2^24 byte memory, what are the lowest and highest addresses if memory is word addressable,
assuming each word is 32 bits?

Q. A computer has 32-bit instructions and 12-bit addresses. Suppose there are 250 2-address
instructions. How many 1-address instructions, if any, can be formulated?

thanks....
