computer architecture.

1. [6] What does the 8-bit binary value 10010110 represent if a computer is using:
   1. Signed magnitude representation?
   2. Signed one's complement representation?
   3. Signed two's complement representation?

2. [6] Using 5 bits, give the range of values (in decimal) that can be represented (i.e., the largest positive number and the smallest negative number), assuming we are using:
   1. Signed magnitude representation
   2. Signed one's complement representation
   3. Signed two's complement representation

3. [6] From the results of the previous question (plus the example we did in class using 3 bits), generalize the range of values (in decimal) that can be represented in x number of bits using:
   1. Signed magnitude representation
   2. Signed one's complement representation
   3. Signed two's complement representation
