What Are Bitwise Operators?

This lesson provides an in-depth discussion about Bitwise operators.

This lesson will help you understand Bitwise operators and how to use them by giving practical examples.

Why use Bitwise operators?

In computer programming, a Bitwise operation operates on one or more bit patterns or binary numerals at the bit level.


  • They are fast and simple action.
  • They are directly supported by the processor.
  • They are used to manipulate values for comparisons and calculations.
  • Bitwise operations are incredibly simple and faster than arithmetic operations.

Bitwise algorithms are used to perform operations at bit-level or to manipulate bits in different ways.

Bitwise operations are much faster and are sometimes used to improve the efficiency of a program.

Remember this

Any indication of a bit’s position is counted from the right (least significant) side to the left.

For example

The binary value 0001 (decimal 1) has zeroes at every position but the first (the rightmost) one.
