BRIEF REVIEW OF

BITWISE LOGICAL

OPERATIONS

AND

The logical AND operation compares 2 bits and if they are both “1”, then the result is “1”, otherwise, the result is “0”.

	0	1
0	0	0
1	0	1

OR

The logical OR operation compares 2 bits and if either or both bits are “1”, then the result is “1”, otherwise, the result is “0”.

	0	1
0	0	1
1	1	1
