4. (6 points, 3 each) Consider a 32-bit hexadecimal number stored in memory as shown in the table below: a. If the machine is big endian and uses 2's complement representation for integers, give the 32-bit integer number (in decimal) starting at address 100. b. If the machine is little endian and the number is an IEEE single precision floating point value, give the decimal equivalent. The number should be written so that the first nonzero value is just to the right of the decimal point (e.g., 0.56 x 103, 0.775 x 10-4). Address 100 101 102 103 Value AA FB 16 09
