Question 5

complete the bit shifts for these calculations using 4 bits
4 OR 1
2 OR 5
3 AND 7
10 AND 12
1 XOR 10
5 XOR 3

Answer 5

0100 | 0001 = 0101 5
0010 | 0101 = 0111 7
0011 & 0111 = 0011 3
1010 & 1100 = 1000 8
0001 ^ 1010 = 1011 11
0101 ^ 0011 = 0110 6

Question 6

complete the bit shifts for these calculations using 6 bits
2 LSHIFT 3
5 LSHIFT 1
12 RSHIFT 1
32 RSHIFT 4

Answer 6

000010 → 010000 16
000101 → 001010 10
001100 → 000110 6
100000 → 000010 2
