+A **bijection**, also known as a one-to-one correspondence, is a [Function](/wiki/Function) that pairs every element from one set with exactly one element from another. This creates a perfect, unique mapping where each element finds a distinct partner, making the function both an [Injection](/wiki/Injection) (one-to-one) and a surjection (onto).
