5. [16 marks] An n-bit register can hold 2^n distinct bit patterns. As such, it can only be used to address a memory whose number of addressable units (typically, bytes) is less than or equal to 2^n. In what follows, use the power-of-two interpretation of Greek prefixes. I.e., K = 2^10, M = 2^20, etc. In this question, register sizes need not be a power of two. a) What is the minimum size of an address register for a computer with 79 GBs of memory? answer = _____ bits b) What is the minimum size of an address register for a computer with 17 TBs of memory? answer = _____ bits c) What is the minimum size of an address register for a computer with 1.05 EBs of memory? answer = _____ bits d) What is the minimum size of an address register for a computer with 0.5 (1/2) EB of memory? answer = _____ bits
