There are situations where we use numbers to load flags , meaning each bit, or set of bits, means something. Or we need to manipulate some data according to their bits, maybe it has to do with colors or something that bits individually end up having a special meaning. In cases like this the simplest way to connect a specific bit knowing in what position it should be. And how to turn it off or reverse its value?

These operators are usually present in most languages with the same semantics, so everything that works here should work for other languages. Several questions talk about this:
