7. We number bit positions from right to left, starting with 0. (a) The rightmost bit of a 16-bit number is what position? (b) The leftmoet bit of a 16-bit number is what position? 8. Fill in the blanks. Explain the following properties of binary numbers. (Again, remember that we number bits from right to left starting with 0). (a) Shifting the digits four to the left is the same as - (b) If the bit in pceition 0 is a I the decimal number is (c) If a number contains all Os except a 1 in position 4 the decimal number is (d) Shifting the digits two to the right is the same as performing by
