Ans 3

another by bit-wise operations is called

1. masking 2. pruning
3. biting 4. chopping

Ans 3
1. masking
    is AND operation to convert a preknown number of digits to 0
    if these are the bits    101100110 and if 4 LSBs are to masked AND it with 111110000

2. pruning

3. biting
4. chopping
