## TL;DR

Bit manipulation works directly with the binary representation of integral values. Common operators include bitwise AND, OR, XOR, complement, and shifts.

## Core Explanation

Bitwise operations are useful when data is naturally represented as flags, masks, packed integers, low-level protocol fields, or hardware registers. The important engineering constraint is type discipline: language documentation usually restricts these operators to integral numeric types and defines how operands are converted before the operation.
