Can someone plz answer these questions

Answer 1

Answer:

11001100 = 204

11111111 = 255

Explanation:

For 11001100:

1*2⁷ + 1*2⁶ + 0*2⁵ + 0*2⁴ + 1*2³ + 1*2² + 0*2¹ + 0*2⁰ = 204

Just replace 1's by 0's in the following calculation to do it for every 8 bit number:

1*2⁷ + 1*2⁶ + 1*2⁵ + 1*2⁴ + 1*2³ + 1*2² + 1*2¹ + 1*2⁰ = 255

If you don't want to do the calculation yourself, you can set the windows calculator in programmer mode, then select binary and key in the number.
