Assume that we have two different computers. One has a word length of 6 bits and the other has a word length of 15 bits. A) What is the range of numbers that can be stored in these computers assuming that the stored data is unsigned (without the sign bit)? B) What is the range of numbers that can be stored in these computers assuming 1’s complement is used to store data? C) What is the range of numbers that can be stored in these computers assuming 2’s complement is used to store data?
