Exercise 2 1- Answer the following: (a) How many nibbles are 16 bits? (b) How many bytes are 32 bits? (c) If a word is defined as 16 bits, how many words is a 64-bit data item? (d) What is the exact value (in decimal) of 1 meg? 2- 1 In a given byte-addressable computer, memory locations 10000H to 9FFFFH are available for user programs. The first location is 10000H and the last loca- tion is 9FFFFH. Calculate the following: (a) The total number of bytes available (in decimal) (b) The total number of kilobytes (in decimal) 3- Find the total amount of memory, in the units requested, for each of the fol- lowing CPUs, given the size of the address buses: (a) 16-bit address bus (in K) (b) 24-bit address bus (in megs) (c) 32-bit address bus (in megabytes and gigabytes) (d) 48-bit address bus (in megabytes, gigabytes, and terabytes)
