bitwise operators

It can be used for solving problems which are in binary. So maybe for creating any logical condition these operators could be used.

any particular example which we need in real life

since programming depends on bytes I would say yes. Multiplication and other math funktions are done this way.

Here's an example 2 in binary is 0010, if you use a logical left shift that is <<2 you get 4, essentially a logical left shift doubles a number.
