RRB Junior Engineer / DMS / CMA 2019 · Question 3717 of 3719
The process of transforming one-bit pattern into another by bitwise operation is called masking. Bitwise operation A bitwise operation operates on one or more-bit patterns or binary numerals at the level of their individual bits. It is a fast, primitive action directly supported by the central processing unit (CPU), and is used to manipulate values for comparisons and calculations. Masking A mask is data that is used for bitwise operations, particularly in a bit field. Using a mask, multiple bits in a byte, nibble, word etc. can be set either on, off or inverted from on to off in a single bitwise operation.
