  1. Twos complement concepts. (10 points)
    1. How many different values can be encoded in a 64-bit word if all values were to be positive integers (i.e., unsigned)? Express your answer as a power of 2. (5 points)
    2. If the 64-bit word now uses 2s complement representation to allow negative numbers as well, does that impact the total number of distinct values that can be encoded? If so, how many distinct values can now be encoded? (5 points)

Please answer the question thoroughly. Thank you!
