Fermions are a class of subatomic particles that follow Fermi-Dirac statistics and obey the Pauli exclusion principle. They are one of the two fundamental categories of particles in quantum mechanics, the other being bosons. Fermions are characterized by having half-integer spin (e.g., 1/2, 3/2, etc.), and they include particles such as electrons, protons, neutrons, and neutrinos.
