Computer systems manipulate bit patterns.
Complete the table with the result of applying the shift to the binary pattern.
| Binary pattern | Shift | 8-bit binary result |
|---|---|---|
| 1000 0111 | Logical shift right by 1 |
Mark scheme
Award one mark for each correct nibble in the correct order:
- 0100 (1)
- 0011 (1)
0 marks if the response is not 8-bit binary.
Example answers and how they were marked
Full marks2/2
0100 0011
Why: Every bit moves 1 place right, with 0s in from the left: both nibbles are correct (2).
Some marks1/2
0100 0010
Why: A slip in the last bit. The first nibble is correct (1); the second is not.
No marks0/2
0000 1110
Why: Shifts the bits the wrong way. Neither nibble is correct.
