What are the differences between rings, groups, and fields?
WEBEvery field is a ring, and the concept of a ring can be thought of as a generalisation of the concept of a field. Alternatively, a field can be conceptualised as a particular kind of ring, one whose non-zero elements form an abelian group under multiplication.

Ring (mathematics) - Wikipedia
In mathematics, rings are algebraic structures that generalize fields: multiplication need not be commutative and multiplicative inverses need not exist. Informally, a ring is a set equipped with two binary operations satisfying properties analogous to those of addition and multiplication of integers. Ring elements may be numbers such as integers or complex numbers, but they may also be non-numerical objects such as polynomials, square matrices, functions, and power series.
