True or False

1. Binary code used to store 72 into one byte as a signed twos complement integer is 10111000.

2. The unsigned integer value, 1320, stored in word 9 if the machine stores words using little endian format for the following bytes are stored in a 16-bit word computer:

byte 0 = 00101000 byte 1 = 00000101

3. Given the 8-bit pattern: 10100001 the decimal value of the signed twos complement integer it represents is -95.

4. The binary 8-bit EXPONENT portion of the 32-bit (single precision) IEEE floating point value of 6.28125 is 10000001.

5. The decimal value -39.75 is stored in 32-bit (single precision) IEEE format, 11000010 00011111 00000000 00000000.

6. Given the 32-bit pattern: 1 01111110 10010000 00000000 0000000 the decimal value of the IEEE floating point value it represents is -0.78125.

7. A 16-bit register contains A7E7 (hex). After a left shift of 3 bits, the hex value would be 9F9C.

8. A 16-bit register contains A7E7 (hex). After a right shift of 3 bits, the hex value would be F4FC.

9. Suppose you have two 8-bit registers, A and B, that contain the values 00001111 and 11100100. If the two registers are combined using the XOR operator, the resulting bit string would be 11101011.

10. Suppose you have two 8-bit registers, A and B, that contain the values 10001111 and 01010101. If the registers are combined using the following operations:

NOT (A OR (NOT B))

The resulting string bits would be: 01010000.

11. Given the signed twos complement 8-bit values 01101110 and 11100100, the 8-bit binary sum is 01010010.

12. Given the signed twos complement 8-bit values 11010001 and 11100100, the decimal value of the difference (subtract the second number from the first number) is -19.
